[Nursing Experience Using Art Therapy to Help Women With Breast Cancer Face Changes in Body Image].

The subject in this study was a female professional painter who underwent bilateral mastectomy because of bilateral breast cancer, experienced postoperative wound scarring, and developed alopecia due to the side effects of chemotherapy, which caused the patient to lose body image confidence and the motivation to engage in artistic creativity. The patient had shed tears early in the intervention and complained of difficulties with body image adjustment due to her altered appearance. Mastectomy patients must not only undergo drug treatment but also adjust psychologically to body image changes to decrease negative emotions. This was the author's motivation for involvement in this case. The nursing period was from 23 September to 30 December 2021. Physical, mental, spiritual, social, and family data were collected using observations and interviews. These data were evaluated and the main problems were determined to be disturbed body image related to altered body perception post-surgery, alopecia caused by chemotherapy, impaired physical mobility due to upper limb mobility limitations post-surgery, and nausea due to chemotherapy. The patient was encouraged to paint again and to use artistic creativity to comfort herself. Moreover, she was guided to express her innermost thoughts to face the impact of her changes in appearance. In addition, a care consultation channel was provided to facilitate experience sharing with other breast cancer patients, thus assisting the patient to cope with the mental impact of her treatments and face subsequent cancer treatments with a more positive attitude. Art therapy embraces a diverse variety of methods, including drawing and music. Art therapy is a valuable tool that facilitates both physical and mental healing. Based on this experience, nurses should include patients' close relatives when performing art therapy to facilitate shared care to overcome difficulties. We hope this nursing experience provides a practical reference for nurses.

Lots of little ones: Analysis of charitable donations to a hospice and palliative care unit in Taiwan.

BACKGROUND: Charitable donations play a major role in the provision of hospice and palliative care (HPC) services, most of which are not reimbursed by health insurance programs. A good understanding of the constitution and use of donations is thus conducive to maintaining a high-quality HPC unit. METHODS: The data sources were the publicly available balance sheet, work report, and donor lists of a foundation exclusively supporting one of the best HPC units in Taiwan in the fiscal year of 2017. The analysis included the donation amounts and frequencies by donor type (individual, corporate, and group) and the categories of expenses. RESULTS: The foundation received 3033 donations worth a total of 7.8 million New Taiwan dollars (NTD) (approximately 258 thousand US dollars) in 2017. Two-thirds of the donations were allocated to the provision of direct care services. Of the 3033 donations, only 11 (0.4%) were worth 100 000 NTD or more, while 108 (3.6%) were valued between 10 000 and 99 999 NTD, 1268 (41.8%) were valued between 1000 and 9999 NTD, and 1646 (54.2%) were worth less than 1000 NTD. Of 1051 donors, 974 (92.7%) were individuals, 378 (36.0%) donated more than once, and 106 (10.1%) donated 12 or more times in one year. CONCLUSION: HPC services in Taiwan are sponsored by lots of individuals and small donations. For sustainability of standards-based and quality HPC services, the benevolence of the public should be thus cherished and adequately responded to.

The effects of a Socially Supportive Activities Program (SSAP) on mood in long term care: A pilot study.

This study examined the effects of a facilitated 10-week Socially Supportive Activities Program (SSAP) designed to improve mood in a geriatric institutional setting. A sample of 68 Taiwanese elders in long-term care facilities with depressive symptoms were randomly assigned to either an experimental group (N = 35) or a control group (N = 33). Outcomes were measured before the intervention, week 1, and at week 12, one-week post intervention. In the experimental group, pre-post measurement results demonstrated significant reductions in depressive symptoms, measured by Geriatric Depression Scale, and significantly higher levels of self-transcendence, measured by the Self-Transcendence Scale. An additional post-intervention measure of mood was collected with the Apparent Emotional Rating Scale. The AERS also demonstrated a significantly higher score (better mood) in the experimental group than in the control group. This study supports the use of a structured, facilitated, well-designed social activities program like the SSAP, to enhance and improve mood in elders who live in long-term care facilities.

The Effectiveness of a Virtual Reality-Based Tai Chi Exercise on Cognitive and Physical Function in Older Adults with Cognitive Impairment.

BACKGROUND: Tai Chi (TC) is a Chinese mind-body exercise with proven physical and psychological benefits. A modified TC via virtual reality (VR) may be suitable for the elderly owing to the immediate guidance and feedback regarding movement accuracy. This study explored the cognitive and physical effects of a VR-based TC (VRTC) exercise program on older adults with cognitive impairment (CI). METHODS: Sixty older adults with CI were cluster-assigned to either the VRTC or the control group; the intervention was conducted twice weekly for 6 months. Outcomes included cognitive and physical functions. The movement accuracy score and attendance were recorded. Generalized estimating equation (GEE) and multiple regression analyses were performed. RESULTS: Adjusted GEE analysis showed significant interaction effects in the 6-min walk test, 30-s sit-to-stand test, functional reach, 5-m gait speed, and abstract thinking and judgment. Overall, medium to large effect sizes (d = 0.50-0.82) were found in favor of the VRTC group. The average movement accuracy score in the first 3 months significantly predicted improvement in cognitive performance (p = 0.011). CONCLUSIONS: The VRTC exercise posed a protective effect for some cognitive and physical functions in older adults with CI. The more engaging the program, the greater the improvement in the cognitive performance.

[Development of the Oral Assessment Scale for Post-Operational Patients With Oral Cancer].

BACKGROUND: Current oral assessment scales are designed to assess the severity of oral health in cancer patients who have undergone radiotherapy or chemotherapy. Currently, no scale is available that assesses the overall oral health situation of patients. However, this type of scale is critical for guiding nursing staff to understand the oral status of postoperative patients and for facilitating the development of patient-centered oral nursing treatments. PURPOSE: To develop the oral assessment scale for post-operational patients with oral cancer (OASPOCa) and establish its psychometric properties. METHODS: The ten associated items of the OASPOCa were determined using a series of five professional council meetings and two verifications of content validity by 5 experts in the field of oral cancer care. A pilot study was conducted on 30 participants and a formal study was conducted on 100 participants at the ICU and the oral and maxillofacial surgery ward at a medical center in southern Taiwan. All of the participants were oral cancer patients who had been admitted to excise tumors of oral cancer. None of the participants had been treated previously for oral cancer using chemotherapy or radiotherapy. The intraclass correlation coefficient (ICC), internal consistency reliability, and concurrent validity of the OASPOCa were evaluated. RESULTS: A content validity of 1.0 was obtained. The inter-rater reliability assessment in the pilot study yielded ICCs of .97 for two assessment items ("lips" and "tongue") and 1.0 for the remaining eight items. The Cronbach's α coefficient was .72 for the OASPOCa. Further, a statistically significant negative relationship was found between overall oral status and oral comfort level (r = -.93, p < .001). CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The oral assessment scale for post-operational patients with oral cancer was found to have good reliability and validity. This scale is a reliable tool for assessing the oral status of postoperative oral cancer patients.

[The Relationship Between Coping Behaviors and Symptom Distress in Elderly Patients With Cancer Undergoing Initial Chemotherapy].

BACKGROUND: Elderly cancer patients undergoing initial chemotherapy often suffer discomfort from medication-related symptom distress. This discomfort may affect treatment responses and outcomes negatively. PURPOSE: This correlational, cross-sectional design study used a purposive sample of 100 patients who were both over 60 years of age and currently undergoing initial chemotherapy. The participants completed a structured questionnaire that was administered at a medical center in southern Taiwan. The questionnaire included a demographics datasheet, Coping Behavior Scale, and Symptom Distress Scale. Data was analyzed using descriptive statistics, Pearson's correlations, Mann-Whitney U, and Kruskal Wallis tests, which were run on SPSS 19.0 software. METHODS: This correlational, cross-sectional design study used a purposive sample of 100 patients who were both over 60 years of age and currently undergoing initial chemotherapy. The participants completed a structured questionnaire that was administered at a medical center in southern Taiwan. The questionnaire included a demographics datasheet, Coping Behavior Scale, and Symptom Distress Scale. Data was analyzed using descriptive statistics, Pearson's correlations, Mann-Whitney U, and Kruskal Wallis tests, which were run on SPSS 19.0 software. RESULTS: Three-quarters (78%) of participants reported that they suffered from more than four distress symptoms. The top distress symptoms in terms of severity included: fatigue, poor appetite, insomnia, dry mouth, and altered bowel habits. The top distress symptoms in terms of frequency included: fatigue, dry mouth, poor appetite, insomnia, and altered bowel habits. "Problem-focused" coping was the most frequent type of coping behavior (mean = 3.19, SD = 0.24) that was used by participants. Furthermore, more frequent use of "emotions-focused" coping behaviors was associated with a greater risk of experiencing serious distress symptoms (r =.44, p < .001). Number of chronic diseases, cancer stage, and type of cancer treatment had no significant influence of symptom distress. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: Findings confirmed the relationship between coping behavior and symptom distress in elderly Taiwanese cancer patients undergoing initial chemotherapy. The results suggest that healthcare providers may use interventions that target patient coping behavior in order to alleviate the chemotherapy-induced symptoms of distress in elderly cancer patients.

The association between participation in social activity and depressive symptoms in institutionalized elders in Taiwan.

Depression can be a significant predictor of rapid health decline in institutionalized elders. Non-pharmacologic interventions for depression may include meaningful and enjoyable social activities. This cross-sectional, descriptive correlational study was to examine the associations between three components (frequency, meaningfulness and enjoyment) of nine types of social activities and depressive symptoms in a sample of Taiwanese elders living in long-term care facilities. Results indicated that meaningful and enjoyable activities were associated with fewer depressive symptoms among institutionalized elders. Clinically depressed elders (GDS score ≥ 6) were significantly less likely to report a sense of meaning in 6 of 9 social activities, or to report as enjoyable 7 of 9 social activities investigated. Findings suggest that elders' contemplate assignation of meaning of their subjective experiences with social activities, and it would behoove clinical nurses to pay attention to the essential purpose and perceived benefit of the designed social activities.

Factors associated with depressive symptoms in older Taiwanese adults in a long-term care community.

BACKGROUND: This study was to examine culturally based factors as potential predictors of depressive symptoms in older Taiwanese adults living in eight long-term care institutions in southern Taiwan. METHOD: A cross-sectional, exploratory design study was used with a purposive sample of 156 participants with a mean age of 79.80 ± 7.14 years. Measurements included filial responsibility expectation questions, two questions about degrees of acceptance of institutionalization, Perceived Stress Scale, Self-Transcendence Scale, and Geriatric Depression Scale. RESULTS: An elder's willingness to be institutionalized, an elder's willingness to remain institutionalized, perceived stress, and self-transcendence were significantly associated with depressive symptoms (r = -0.35; -0.49; 0.60; and -0.67, respectively). Although no evidence for the relationship between filial responsibility and depressive symptoms was found in this study, there was evidence that filial responsibility was highly valued. Self-transcendence was the strongest predictor of depressive symptoms, accounting for 45% of the variance. CONCLUSION: These findings provide insight into the cultural factors associated with depressive symptoms and support the need of timely interventions for institutionalized Taiwanese elderly population.

Effects of Gum Chewing on Recovery From Postoperative Ileus: A Randomized Clinical Trail.

BACKGROUND: Sham feeding with products such as chewing gum has been theorized to decrease the incidence and time to resolution of postoperative ileus. The conflicting findings in the literature on this subject are because in part of the use of mixed study populations, which has led to difficulties in assessing the value of sham feeding in ameliorating this condition. PURPOSE: The aim of this study was to evaluate the efficacy of postsurgical gum chewing in restoring normal bowel movement in patients with colorectal cancer who had undergone abdominal surgery for colon resection. METHODS: A randomized controlled trial was used to examine the time to first postoperative flatus and defecation. The intervention group ( n = 30) received xylitol chewing gum on the first day after colon resection, one piece of gum for 15 minutes, 3 times daily, until the time to first flatus and defecation. Both the intervention and control groups ( n = 30) received standard postoperative care and were encouraged to walk as soon as possible after surgery. The time to first flatus was reported by patients. RESULTS: The time to first flatus and defecation in the intervention group was significantly shorter than that in the control group (39.13 ± 15.66 vs. 52.92 ± 21.97 hours and 54.55 ± 18.90 vs. 77.98 ± 34.59 hours, respectively). However, after controlling for age and surgical duration, only time to first flatus was significantly shorter in the intervention group. Significantly positive correlations were found between time to first flatus and time to first defecation in both groups. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: In this study, gum chewing was shown to have a positive effect on the time to first postoperative flatus and defecation. This inexpensive and noninvasive intervention may be recommended to decrease the time to resolution of postsurgical ileus in middle-aged and older patients who have undergone open abdominal surgery for colorectal resection.

In-kind donations to healthcare facilities during COVID-19: Experiences from a large medical center in northern Taiwan.

BACKGROUND: In early 2020, a global outbreak of 2019 novel coronavirus disease (COVID-19) caused high mortality rates and public panic. Worldwide demand for personal protective equipment has risen, with diminishing supplies and shortages reported. During the pandemic, charitable donations have been made by the public, aimed at helping medical staff. Based on the open data, we investigate the charitable in-kind donations received by a large medical center in northern Taiwan (Taipei Veterans General Hospital [TPEVGH]) in Taiwan during the pandemic. METHODS: The period of investigation was the first half of the year 2020. TPEVGH has received various public donations. The list of donations published on the hospital's official website was analyzed. The variables in the analysis were donation category, donation percentage, number of donations, and total donation amount. RESULTS: Most in-kind donations were food and beverages (55.1%), with a monetary value of 3 124 510 New Taiwan Dollars (NTD) (24.3%). Medical equipment accounted for the second-highest number of items (34.8%) but was the highest monetary value (70.6%; 9 275 945 of 12 875 855 NTD). Daily necessities accounted for the lowest number of items (10.1%) and had a total monetary value of 475 400 NTD (3.7%). Over two-thirds were beverages (68.4%), all of which were bottles or cans for easy storage. Despite only five items (13.2%) being juice, the donation size was the largest, accounting for nearly half (47.1%) of the total monetary value. Only one item was fruit, which was high-class organic apples. The monetary value of this item was the highest (7.8%) among all donated food. Most donated snacks were biscuits. CONCLUSION: During the COVID-19 pandemic, most public donations to TPEVGH were food and daily necessities. While every donation should be appreciated, accepting high volumes of donations might incur donation management problems. Further research could be focused on managerial aspects, for example, quality and safety checking, storage, and distribution.

Analysis of the Content and Comprehensiveness of Dermatology Residency Training Websites in Taiwan.

With a growing trend in the popularity of web-based resources, it is important to evaluate residency program websites for providing accurate information for dermatology residency applicants. Little is known about the quality of dermatology residency websites in Taiwan. The aim of the study is to assesses the quality of official websites of dermatology training programs in Taiwan. A literature search for all related studies from inception to 31 July 2020 was performed using PubMed without restriction on language. We used criteria that had 6 domains and 25 items to evaluate 23 official websites of the dermatology training programs in Taiwan from August to September 2020. Of the 23 training programs, only 6 (26%) of the websites met more than half of the criteria. Notably, the items "features of the department" and "comprehensive faculty listing" were included in all websites. The criteria for interview process, board pass rates, social activities and information on the surrounding area were not met by all websites. Evidently, there is much room for improvement for the dermatology training program websites in Taiwan.

Nurse managers' decisions: fast and favoring remediation.

How do nurse managers make decisions about quality issues on their units? We asked 10 nurse managers in 3 Arizona hospitals to describe how they resolved a recent quality issue. The managers tended to use a linear, but cognitively expensive strategy, often jumping from problem to solution without a clear goal and selecting solutions biased toward remedial education. Decision support tools should help managers think more systemically and efficiently, while encouraging consideration of more alternatives to reach targeted goals.

To Work at Clinics or at Hospitals? Analysis of Family Physician Recruitment Advertising in Taiwan.

Family physicians act as gatekeepers of the healthcare system and have an indispensable role in providing holistic care in the primary care system. While previous studies had focused on the geographic maldistribution of family physicians, the current study investigated the distribution of job opportunities for family physicians by analyzing recruitment advertisements posted in medical association journals, as an indirect way to observe the marketplace demand for physicians. We collected all the recruitment advertisements for family physicians in the twelve issues of the Taiwan Medical Journal, the official organ of the Taiwan Medical Association, in 2018. In contrast to 124 new trainees annually, 739 advertisements for family physicians were posted within the entire year. After eliminating repeated advertisements, there were 302 distinct advertisements, of which hospitals accounted for 18.9% (n = 57). The job opportunities at hospitals were offered mainly by regional hospitals (n = 26) and community hospitals (n = 29), but only two by medical centers. Family physicians in Taiwan were in great demand not only by primary care clinics but also by hospitals. The role of family physicians in hospitals is worth further study.

Visiting Policies of Hospice Wards during the COVID-19 Pandemic: An Environmental Scan in Taiwan.

During an epidemic, almost all healthcare facilities restrict the visiting of patients to prevent disease transmission. For hospices with terminally ill patients, the trade-off between compassion and infection control becomes a difficult decision. This study aimed to survey the changes in visiting policy for all 76 hospice wards in Taiwan during the COVID-19 pandemic in March 2020. The altered visiting policies were assessed by the number of visitors per patient allowed at one time, the daily number of visiting slots, the number of hours open daily, and requisites for hospice ward entry. The differences in visiting policies between hospice wards and ordinary wards were also investigated. Data were collected by reviewing the official website of each hospital and were supplemented by phone calls in cases where no information was posted on the website. One quarter (n = 20) of hospice wards had different visiting policies to those of ordinary wards in the same hospital. Only one hospice ward operated an open policy, and in contrast, nine (11.8%) stopped visits entirely. Among the 67 hospice wards that allowed visiting, at most, two visitors at one time per patient were allowed in 46 (68.6%), one visiting time daily was allowed in 32 (47.8%), one hour of visiting per day was allowed in 29 (43.3%), and checking of identity and travel history was carried out in 12 wards (17.9%). During the COVID-19 pandemic, nearly all hospice wards in Taiwan changed their visiting policies, but the degree of restriction varied. Further studies could measure the impacts of visiting policy changes on patients and healthcare professionals.

Hospital visiting policies in the time of coronavirus disease 2019: A nationwide website survey in Taiwan.

BACKGROUND: Coronavirus disease 2019 (COVID-19), a novel infectious coronavirus disease, has become a worldwide pandemic. Infection control precautions for hospital visitors are needed to avoid cluster outbreaks, so this study investigated the visiting policies of all the hospitals in Taiwan in the time of COVID-19. METHODS: From March 15, 2020, to March 18, 2020, we searched the official websites of all 472 National Health Insurance-contracted hospitals to determine their visiting policies. For those hospitals that had posted new visiting policies and still allowed visits to ordinary wards, we recorded the relevant details shown on their websites, including the number of visitors allowed at one time, the number of visiting slots per day, the total visiting hours per day, and the rules provided to visitors before visiting. RESULTS: During the study period, 276 (58.5%) hospitals had posted new visiting policies on their websites, with higher proportions of academic medical centers (92.0%, 23/25) and metropolitan hospitals (91.5%, 75/82) than local community hospitals (48.8%, 178/365) doing so. Visits to ordinary wards were forbidden in 83 hospitals among those. Among the 193 hospitals that had new visiting policies and still allowed visits to ordinary wards, 73.1% (n = 141) restricted visitors to two at a time and 54.9% (n = 106) restricted visits to two visiting slots per day. Furthermore, history taking regarding travel, occupation, contacts, and cluster information was mentioned by 82.4% (n = 159) of these 193 hospitals, body temperature monitoring by 78.2% (n = 151), hand hygiene by 63.2% (n = 122), and identity checks by 51.8% (n = 100). CONCLUSION: In the time of COVID-19 covered by this study, about three-fifths of the hospitals in Taiwan had posted their visiting policies for ordinary wards on their websites. Furthermore, the thoroughness with which such visiting policies have been enforced also requires investigation.

Web Search Trends of Implementing the Patient Autonomy Act in Taiwan.

BACKGROUND: The Patient Autonomy Act was implemented in Taiwan on 6 January 2019. It is the first patient-oriented act in Taiwan, and also the first special act to completely protect patient autonomy in Asia. Our study aimed to investigate the web resources citizens were able to access on the eve of the implementation of the Patient Autonomy Act in Taiwan. METHODS: Patient Autonomy Act-related web resources were searched for by entering 10 related terms individually into the Google search engine in January 2019 and again in April 2019. Search activity data were analyzed using Google Trends. RESULTS: "Advance care planning" and "advance decision" were the most relevant keywords for finding information about the Patient Autonomy Act on the eve of the act's implementation in Taiwan. The main online information sources were non-governmental websites including news sites and online magazines. The related search volume only increased on the eve of implementation. CONCLUSIONS: Even though the Patient Autonomy Act was first published three years before its implementation, the related search volume only increased on the eve of its implementation. Therefore, whether the three-year buffer between its publication and implementation was necessary requires further investigation.

In the Name of Family Medicine: A Nationwide Survey of Registered Names of Family Medicine Clinics in Taiwan.

Family medicine is officially a specialty, but is often not regarded as a specialty by the general public. Past studies have usually investigated the opinions of medical students and resident physicians regarding family medicine, whereas few have focused on practicing family physicians themselves, especially in terms of analyzing how they represent themselves. This study aimed to investigate the patterns of clinic names to better apprehend whether general practitioners see themselves as being on an equal footing with other medical specialists. The registered names, medical specialties, and levels of urbanization of all clinics of Western medicine in Taiwan were collected. For clinics of each specialty, we examined whether their names contained the corresponding specialty designation. For example, a family medicine clinic was checked to determine whether its name contained the term "family medicine" or its abbreviation. The naming of family medicine clinics was then compared with that of clinics with other specialties. Of the 9867 Western medicine clinics included in this study, two-thirds (n = 6592) were single-specialty clinics. In contrast to the high percentages of single-specialty clinics of other specialties with specialty-containing names (97.5% for ophthalmology, 94.8% for dermatology, and 94.7% for otolaryngology), only 13.3% (132/989) of the family medicine clinics had such names. In addition, the urban family medicine clinics had a higher proportion (15.2%, 74/487) of specialty-containing names than the suburban (12.6%, 44/349) and rural family medicine clinics (9.2%, 14/153). Overall, a low percentage of family medicine clinics in Taiwan included "family medicine" in their names. This issue of professional identity deserves further qualitative investigation.

Physical, affective, and behavioral effects of group reminiscence on depressed institutionalized elders in Taiwan.

BACKGROUND: Depression among institutionalized elders is a common problem associated with physical and functional limitations, and effective interventions are needed. OBJECTIVE: The objective of this study was to determine the effect of group reminiscence on physical function, behavioral competence, and depression among clinically depressed, institutionalized elders. METHODS: A two-group, random-assignment quasi-experimental study was conducted in four long-term care facilities in southern Taiwan. The experimental group (n = 21) received six to eight group reminiscence sessions over 2 months compared with a routine care control group (n = 24). Outcome measurements included the Behavioral Rating Scale, Barthel's Index, and the Geriatric Depression Scale-short form. RESULTS: Reminiscence sessions resulted in a significant 2-point decrease in the Geriatric Depression Scale-short form (p = .002) and improved behavioral competence (p = .001). No change was identified in functional ability. CONCLUSIONS: Group reminiscence is a therapeutic intervention for depressed, institutionalized elders that can be managed by trained nursing staff. It is a cost-effective approach to improve psychosocial well-being for institutionalized older people. Additional research is needed on a larger sample across different diseases and cultural groups.

Official Websites of Local Health Centers in Taiwan: A Nationwide Study.

Local health centers (LHCs) play a key role in public health. Because it has now become popular to seek health information on the Internet, an effective website is indispensable to an LHC. Our study aimed to survey the official websites of LHCs in Taiwan with an evaluation framework. All 369 LHCs in Taiwan were surveyed in March 2018. The evaluation indicators included health information, online interactive services, technical features, institutional information, links to external resources, website management, the last updated time, and number of visitors. The indicators were stratified by the urbanization levels of the LHCs. In total, 98.0% (n = 360) of the LHCs had official websites. The majority (n = 241) of the websites were updated within the past 30 days, and most of the websites (n = 353) provided health information. However, the information provided varied considerably. Few LHCs (n = 31) provided online interactive services in terms of an online appointment function. In terms of providing online consultation services, rural LHCs outperformed suburban and urban LHCs (16.4% versus 14.5% and 6.0%, respectively). Most LHCs in Taiwan do not seem to take full advantage of the Internet, with their websites typically serving as static bulletin boards instead of new channels of communication. Further studies could focus on the effectiveness of these websites.

Analytical separation of Au/Ag core/shell nanoparticles by capillary electrophoresis.

This paper demonstrates that capillary electrophoresis (CE) can be employed for characterizing the sizes of a series of Au/Ag core/shell nanoparticles (NPs). We effected the CE separation of Au/Ag core/shell NPs using a mixed buffer of sodium dodecyl sulphate (SDS) (40 mM) and 3-(cyclohexylamino)propanesulfonic acid (10 mM) at pH 9.7 and an applied voltage of 20 kV. A linear relationship (R(2)>0.99) existed between the electrophoretic mobilities and the sizes of the Au/Ag core/shell NPs within the diameter range from 25 to 90 nm; the relative standard deviations of these electrophoretic mobilities were <0.9%. From the good correlation between the results obtained by CE and those provided by scanning electron microscopy, we confirmed that this CE method is a valid one for characterizing the sizes of Au/Ag core/shell NP samples. In addition, when the Au/Ag core/shell NPs were separated through CE and detected using an on-line photodiode array detector, this approach allowed the chemical characterization of the NP species. This CE approach should allow the rapid and cost-effective characterization of a number of future nanomaterials.
