Micro-nanoemulsion and nanoparticle-assisted drug delivery against drug-resistant tuberculosis: recent developments.

Tuberculosis (TB) is a major global health problem and the second most prevalent infectious killer after COVID-19. It is caused by Mycobacterium tuberculosis (Mtb) and has become increasingly challenging to treat due to drug resistance. The World Health Organization declared TB a global health emergency in 1993. Drug resistance in TB is driven by mutations in the bacterial genome that can be influenced by prolonged drug exposure and poor patient adherence. The development of drug-resistant forms of TB, such as multidrug resistant, extensively drug resistant, and totally drug resistant, poses significant therapeutic challenges. Researchers are exploring new drugs and novel drug delivery systems, such as nanotechnology-based therapies, to combat drug resistance. Nanodrug delivery offers targeted and precise drug delivery, improves treatment efficacy, and reduces adverse effects. Along with nanoscale drug delivery, a new generation of antibiotics with potent therapeutic efficacy, drug repurposing, and new treatment regimens (combinations) that can tackle the problem of drug resistance in a shorter duration could be promising therapies in clinical settings. However, the clinical translation of nanomedicines faces challenges such as safety, large-scale production, regulatory frameworks, and intellectual property issues. In this review, we present the current status, most recent findings, challenges, and limiting barriers to the use of emulsions and nanoparticles against drug-resistant TB.

Exploring non-cytotoxic, antioxidant, and anti-inflammatory properties of selenium nanoparticles synthesized from Gymnema sylvestre and Cinnamon cassia extracts for herbal nanomedicine.

The increasing need for pharmaceutical agents that possess attributes such as safety, cost-effectiveness, environmental sustainability, and absence of side effects has driven the advancement of nanomedicine research, which lies at the convergence of nanotechnology and medicine. AIMS AND OBJECTIVES: The study aimed to synthesize non-toxic selenium nanoparticles (SeNPs) using Gymnema sylvestre (G. sylvestre) and Cinnamon cassia (C. cassia) extracts. It also sought to develop and evaluate versatile nanomedicine formulations i.e. selenium nanoparticles of G. sylvestre and C. cassia (SeNPs), drug (lupeol) loaded SeNPs (DLSeNPs), drug-loaded and coated (PEG) SeNPs (DLCSeNPs) without side effects. METHODS: The SeNPs formulations were hydrothermally synthesized, loaded with lupeol to improve efficacy, coated with polyethylene glycol (PEG) for targeted delivery, and characterized using UV-Vis spectrophotometry, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), zeta potential analysis, size distribution analysis, and X-ray diffraction (XRD). Hemolytic cytotoxicity, 2,2-Diphenyl-1-picrylhydzayl (DPPH), total Reducing power, and total antioxidant capacity (TAC) antioxidant assays, carrageenan-induced paw edema, and histological studies were used to estimate the acute anti-inflammatory activity of the synthesized SeNPs. RESULTS: The final form of PEGylated and drug (lupeol)-loaded selenium nanoparticles (DLCSeNPs) exhibited an average particle size ranging from 100 to 500 nm as evidenced by SEM, and Zeta potential results. These nanoparticles demonstrated no cytotoxic effects and displayed remarkable antioxidant (IC50 values 19.29) and anti-inflammatory capabilities. These results were fed into Graph-pad Prism 5 software and analyzed by one-way ANOVA, followed by Tukey's post hoc test (p < 0.001). All nano-formulations exhibited significant overall antioxidant activity, with IC50 values ≤ 386 (p < 0.05) as analyzed by ANOVA. The study's results suggest that G. sylvestre outperformed C. cassia in terms of reducing 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free radical, potassium ferricyanide, and ammonium molybdate in respective antioxidant assays. As far as anti-inflammatory activities are concerned drug (lupeol)-loaded and PEG-coated G. sylvestre SeNPs exhibited the highest anti-inflammatory potential from all other nano-formulations including drug (lupeol)-loaded and PEG-coated C. cassia SeNPs, as exhibited to reduce the release of pro-inflammatory signals i.e. cytokines and NF-kB, making them innovative anti-inflammatory nanomedicine. CONCLUSION: The study synthesized lupeol-loaded and PEG-coated SeNPs, showcasing the potential for biocompatible, cost-effective anti-inflammatory nanomedicines. G. Sylvester's superior antioxidant and anti-inflammatory performance than Cinnamon cassia emphasizes medicinal plant versatility.

Mesenchymal stem cell-derived exosomes as cell free nanotherapeutics and nanocarriers.

Many strategies for regenerating the damaged tissues or degenerating cells are employed in regenerative medicine. Stem cell technology is a modern strategy of the recent approaches, particularly the use of mesenchymal stem cells (MCSs). The ability of MSCs to differentiate as well as their characteristic behaviour as paracrine effector has established them as key elements in tissue repair. Recently, extracellular vesicles (EVs) shed by MSCs have emerged as a promising cell free therapy. This comprehensive review encompasses MSCs-derived exosomes and their therapeutic potential as nanotherapeutics. We also discuss their potency as drug delivery nano-carriers in comparison with liposomes. A better knowledge of EVs behaviour in vivo and of their mechanism of action are key to determine parameters of an optimal formulation in pilot studies and to establish industrial processes.

miRNAs are now starring in "No Time to Die: Overcoming the chemoresistance in cancer".

Cancer is a leading cause of death globally, with about 19.3 million new cases reported each year. Current therapies for cancer management include-chemotherapy, radiotherapy, and surgery. However, they are loaded with side effects and tend to cause toxicity in the patient's body posttreatment, ultimately hindering the response towards the treatment building up resistance. This is where noncoding RNAs such as miRNAs help provide us with a helping hand for taming the chemoresistance and providing potential holistic cancer management. MicroRNAs are promising targets for anticancer therapy as they perform critical regulatory roles in various signaling cascades related to cell proliferation, apoptosis, migration, and invasion. Combining miRNAs and anticancer drugs and devising a combination therapy has managed cancer well in various independent studies. This review aims to provide insights into how miRNAs play a mechanistic role in cancer development and progression and regulate drug resistance in various types of cancers. Furthermore, next-generation novel therapies using miRNAs in combination with anticancer treatments in multiple cancers have been put forth and how they improve the efficacy of the treatments. Exemplary studies currently in the preclinical and clinical models have been summarized. Ultimately, we briefly talk through the challenges that come forward with it and minimize them.

Chemico-biological aspects of (-)-epigallocatechin-3-gallate (EGCG) to improve its stability, bioavailability and membrane permeability: Current status and future prospects.

Natural products have been a bedrock for drug discovery for decades. (-)-Epigallocatechin-3-gallate (EGCG) is one of the widely studied natural polyphenolic compounds derived from green tea. It is the key component believed to be responsible for the medicinal value of green tea. Significant studies implemented in in vitro, in cellulo, and in vivo models have suggested its anti-oxidant, anti-cancer, anti-diabetic, anti-inflammatory, anti-microbial, neuroprotective activities etc. Despite having such a wide array of therapeutic potential and promising results in preclinical studies, its applicability to humans has encountered with rather limited success largely due to the poor bioavailability, poor membrane permeability, rapid metabolic clearance and lack of stability of EGCG. Therefore, novel techniques are warranted to address those limitations so that EGCG or its modified analogs can be used in the clinical setup. This review comprehensively covers different strategies such as structural modifications, nano-carriers as efficient drug delivery systems, synergistic studies with other bioactivities to improve the chemico-biological aspects (e.g., stability, bioavailability, permeability, etc.) of EGCG for its enhanced pharmacokinetics and pharmacological properties, eventually enhancing its therapeutic potentials. We think this review article will serve as a strong platform with comprehensive literature on the development of novel techniques to improve the bioavailability of EGCG so that it can be translated to the clinical applications.

Exploring the use of niosomes in cosmetics for efficient dermal drug delivery.

Dermal drug delivery has emerged as a promising alternative to traditional methods of drug administration due to its non-invasive nature and ease of use. However, the stratum corneum, the outermost layer of the skin, presents a significant barrier to drug penetration. Niosomes, self-assembled vesicular structures composed of nonionic surfactants and cholesterol, have been extensively investigated as a means of overcoming this barrier and improving the efficacy of dermal drug delivery. This review summarizes the current state of research on the use of niosomes in dermal drug delivery in cosmetics, with a particular focus on their formulation, characterization, and application in the delivery of various drug classes. The review highlights the advantages of niosomes over conventional drug delivery methods, including improved solubility and stability of drugs, controlled release, and enhanced skin permeation. The review also discusses the challenges associated with niosome-based drug delivery, such as their complex formulation and optimization, and the need for further studies on their long-term safety and toxicity.

Therapeutic Potential of Nanocarrier-Mediated Delivery of Phytoconstituents for Wound Healing: Their Current Status and Future Perspective.

The treatment of wounds is a serious problem all over the world and imposes a huge financial burden on each and every nation. For a long time, researchers have explored wound dressing that speeds up wound healing. Traditional wound dressing does not respond effectively to the wound-healing process as expected. Therapeutic active derived from plant extracts and extracted bioactive components have been employed in various regions of the globe since ancient times for the purpose of illness, prevention, and therapy. About 200 years ago, most medical treatments were based on herbal remedies. Especially in the West, the usage of herbal treatments began to wane in the 1960s as a result of the rise of allopathic medicine. In recent years, however, there has been a resurgence of interest in and demand for herbal medicines for a number of reasons, including claims about their efficacy, shifting consumer preferences toward natural medicines, high costs and negative side effects of modern medicines, and advancements in herbal medicines brought about by scientific research and technological innovation. The exploration of medicinal plants and their typical uses could potentially result in advanced pharmaceuticals that exhibit reduced adverse effects. This review aims to present an overview of the utilization of nanocarriers in plant-based therapeutics, including its current status, recent advancements, challenges, and future prospects. The objective is to equip researchers with a comprehensive understanding of the historical background, current state, and potential future developments in this emerging field. In light of this, the advantages of nanocarriers based delivery of natural wound healing treatments have been discussed, with a focus on nanofibers, nanoparticles, nano-emulsion, and nanogels.

A DNA Logic Circuit Equipped with a Biological Amplifier Loaded into Biomimetic ZIF-8 Nanoparticles Enables Accurate Identification of Specific Cancers In Vivo.

DNA logic circuits (DLC) enable the accurate identification of specific cell types, such as cancer cells, but they face the challenges of weak output signals and a lack of competent platforms that can efficiently deliver DLC components to the target site in the living body. To address these issues, we rationally introduced a cascaded biological amplifier module based on the Primer Exchange Reaction inspired by electronic circuit amplifier devices. As a paradigm, three abnormally expressed Hela cell microRNAs (-30a, -17, and -21) were chosen as "AND" gate inputs. DLC response to these inputs was boosted by the amplifier markedly enhancing the output signal. More importantly, the encapsulation of DLC and amplifier components into ZIF-8 nanoparticles resulted in their efficient delivery to the target site, successfully distinguishing the Hela tumor subtype from other tumors in vivo. Thus, we envision that this strategy has great potential for clinical cancer diagnosis.

Amphiphilic Metallodrug Assemblies with Red-Light-Enhanced Cellular Internalization and Tumor Penetration for Anticancer Phototherapy.

Metallodrugs are widely used in cancer treatment. The modification of metallodrugs with polyethylene glycol (PEGylation) prolongs blood circulation and improves drug accumulation in tumors; it represents a general strategy for drug delivery. However, PEGylation hinders cellular internalization and tumor penetration, which reduce therapeutic efficacy. Herein, the red-light-enhanced cellular internalization and tumor penetration of a PEGylated anticancer agent, PEGylated Ru complex (Ru-PEG), are reported upon. Ru-PEG contains a red-light-cleavable PEG ligand, anticancer Ru complex moiety, and fluorescent pyrene group for imaging and self-assembly. Ru-PEG self-assembles into vesicles that circulate in the bloodstream and accumulate in the tumors. Red-light irradiation induces dePEGylation and changes the Ru-PEG vesicles to large compound micelles with smaller diameters and higher zeta potentials, which enhance tumor penetration and cellular internalization. Red-light irradiation also generates intracellular 1 O2 , which induces the death of cancer cells. This work presents a new strategy to enhance the cellular internalization and tumor penetration of anticancer agents for efficient phototherapy.

Advances in Delivery of Chemotherapeutic Agents for Cancer Treatment.

Presently, most of the treatment strategies for cancer are focused on the surgical removal of cancerous tumors, along with physical and chemical treatment such as radiotherapy and chemotherapy, respectively. The primary issue associated with these methods is the inhibition of normal cell growth and serious side effects associated with systemic toxicity. The traditional chemotherapeutics which were delivered systemically were inadequate and had serious dose limiting side effects. Recent advances in the development of chemotherapeutics have simultaneously paved the way for efficient targeted drug delivery. Despite the advances in the field of oncogenic drugs, several limitations remain, such as early blood clearance, acquired resistance against cytotoxic agents, toxicity associated with chemotherapeutics, and site-specific drug delivery. Hence, this review article focuses on the recent scientific advancements made in different types of drug delivery systems, including, organic nanocarriers (polymers, albumins, liposomes, and micelles), inorganic nanocarriers (mesoporous silica nanoparticles, gold nanoparticles, platinum nanoparticles, and carbon nanotubes), aptamers, antibody-drug conjugates, and peptides. These targeted drug delivery approaches offer numerous advantages such as site-specific drug delivery, minimal toxicity, better bioavailability, and an increased overall efficacy of the chemotherapeutics.

Quantification of low-content encapsulated active cosmetic ingredients in complex semi-solid formulations by means of attenuated total reflectance-infrared spectroscopy.

Attenuated total reflectance-infrared (ATR-IR) spectroscopy is a robust tool for molecular characterisation of matter. Applied to semi-solid formulations, it enables rapid and reliable data collection without pre-analytical requirements. Based on nano-encapsulated Omegalight®, a skin-lightening active cosmetic ingredient (ACI), incorporated in a hydrogel, it is first demonstrated that, despite the high water content and the chemical complexity of the samples (i.e. number of ingredients), the spectral features of the ACI can be detected and monitored. Secondly, with a total of 105 samples divided into a training set (n = 60) and an unknown set (n = 45) covering a 0.5% w/w-5% w/w concentration range, the study further investigates the quantitative performance of ATR-IR coupled with partial least squares regression (PLSR). Through a step-by-step approach in testing different cross-validation protocols, accuracy (root mean square error of cross-validation (RMSECV)) and linearity between the experimental and predicted concentrations (R2) of ATR-IR are consistently evaluated to be respectively 0.097% (w/w) and 0.995 with a lower LOD = 0.067% (w/w). Subsequently, further evaluation of the accuracy (relative error of the predicted concentration compared with the true value, expressed as %) of the analysis was undertaken with the 45 unknown samples that were defined as unknown and analysed by PLSR. The outcome of the analysis demonstrates the ruggedness and the consistency of the determination performed using the ATR-IR data. With an average relative error of 2.5% w/w and only 5 samples out of 45 blind samples exhibiting a relative error above the 5% threshold, high accuracy quantification of the nano-encapsulated ACI can be unambiguously achieved by means of the label-free and non-destructive technique of ATR-IR spectroscopy. Ultimately, the study demonstrates that the analytical capabilities of ATR-IR hold significant potential for applications in the cosmetics industry, and although the path remains long, the present study is one step further to support validation of the technique, albeit for the specific case of Omegalight®.

Advances in Therapeutic Implications of Inorganic Drug Delivery Nano-Platforms for Cancer.

Numerous nanoparticles drug delivery systems for therapeutic implications in cancer treatment are in preclinical development as conventional chemotherapy has several drawbacks. A chemotherapeutic approach requires high doses of chemotherapeutic agents with low bioavailability, non-specific targeting, and above all, development of multiple drug resistance. In recent years, inorganic nano-drug delivery platforms (NDDPs; with a metal core) have emerged as potential chemotherapeutic systems in oncology. One of the major goals of developing inorganic NDDPs is to effectively address the targeted anti-cancer drug(s) delivery related problems by carrying the therapeutic agents to desired tumors sites. In this current review, we delve into summarizing the recent developments in targeted release of anti-cancer drugs loaded in inorganic NDDPs such as mesoporous silica nanoparticles, carbon nanotubes, layered double hydroxides, superparamagnetic iron oxide nanoparticles and calcium phosphate nanoparticles together with highlighting their therapeutic performance at tumor sites.

[Nanometer preparation of traditional Chinese medicine for rheumatoid arthritis].

Rheumatoid arthritis( RA) is a chronic autoimmune disease,which can occur at any age. Repeated severe attacks can cause joint deformities. Its pathogenesis is complex,and the pathophysiological process involves many different types of cells. At present,the pathogenesis of RA is still unclear,and the clinical medication mainly aims to alleviate inflammation and symptoms.DMARDs,non-steroidal anti-inflammatory drugs,adrenocortical hormones,biological agents and traditional Chinese medicine are all applied in clinic.

In this paper,traditional Chinese and western medicines and their nano-preparations used in the treatment of RA were reviewed in the past five years. The researches of nano-preparation were discussed in terms of pharmacology category. This paper provided reference for the research and development of new-type nano-preparation with outstanding clinical efficacy.

Pursuing Intracellular Pathogens with Hyaluronan. From a 'Pro-Infection' Polymer to a Biomaterial for 'Trojan Horse' Systems.

Hyaluronan (HA) is among the most important bioactive polymers in mammals, playing a key role in a number of biological functions. In the last decades, it has been increasingly studied as a biomaterial for drug delivery systems, thanks to its physico-chemical features and ability to target and enter certain cells. The most important receptor of HA is 'Cluster of Differentiation 44' (CD44), a cell surface glycoprotein over-expressed by a number of cancers and heavily involved in HA endocytosis. Moreover, CD44 is highly expressed by keratinocytes, activated macrophages and fibroblasts, all of which can act as 'reservoirs' for intracellular pathogens. Interestingly, both CD44 and HA appear to play a key role for the invasion and persistence of such microorganisms within the cells. As such, HA is increasingly recognised as a potential target for nano-carriers development, to pursuit and target intracellular pathogens, acting as a 'Trojan Horse'. This review describes the biological relationship between HA, CD44 and the entry and survival of a number of pathogens within the cells and the subsequent development of HA-based nano-carriers for enhancing the intracellular activity of antimicrobials.

Inorganic Nano-Targeted Drugs Delivery System and Its Application of Platinum-Based Anticancer Drugs.

As one of the most important anticancer drugs, cisplatin and its analogues have been widely used in chemotherapy regimens of various tumors. However, a series of side effects and resistance/cross-resistance have been becoming the main obstacles which limit their application and effectiveness. Recent researches suggest that inorganic nano-materials which act as targeted drug delivery carriers of platinum-based anticancer drugs not only enhance the antitumor activity of platinum-based drugs, but also reduce the side effects and resistance. The nano-targeted drugs delivery system provides a new strategy in clinical application of platinum-based anticancer drugs. This review will focus on recent advances in inorganic nano-carriers for platinum-based targeted drugs delivery system.

Biocompatible silver nanoparticles reduced from Anethum graveolens leaf extract augments the antileishmanial efficacy of miltefosine.

Despite the existence of chemotherapy, there is no effective cure for leishmaniasis. In the light of recommended therapeutic regimen is attributed for toxicity and development of clinical resistance, exploration of an efficient method of drug delivery could be one of the option in reducing the dosage and toxicity of drugs. This work is aimed in such fashion to study the enhanced antileishmanial activity of miltefosine with silver-nanoparticles (AgNPs) synthesized by using Anethum graveolens (dill) leaf extract as reducing agent. AgNPs were synthesized in a single step process and characterized by UV-visible, X-ray diffraction (XRD), Fourier transform infra-red spectroscopy (FTIR) to understand the crystal structure and functional groups on their surface. TEM analysis showed that the synthesized AgNPs are of an average size of 35 nm. By performing MTT assay, we found that, AgNPs (between 20 and 100 µM) are biocompatible in nature through pertaining >80% viability of macrophages. Furthermore, AgNPs alone (50 µM) have not shown antileishmanial effect on promastigote stage of Leishmania parasite but in combination with miltefosine (12.5 µM and 25 µM), it magnifies the leishmanicidal effect of miltefosine by ∼2-folds (i.e. AgNPs cut down the IC50 of miltefosine about to half). Scanning electron microscopic (SEM) observation for morphological aberration and genomic DNA fragmentation in promastigotes confirmed the enhanced effect of meltefosine in combination with AgNPs (50 µM AgNPs plus 12.5 µM miltefosine). Similarly, this combination has likely shown a slight augmentation (p = 0.057) of miltefosine (2.5 µM) leishmanicidal efficacy on amastigote stage of the parasite in infected human macrophages by reducing their intracellular growth.

Laboratory study: Synthesis and optimization of nano nisomes containing Bunium persicum essential oil and investigating its toxicity on Trichomonas vaginalis parasite and HFF cell line.

The use of nanotechnology can reduce the challenges facing the use of herbal compounds in the fight against infectious agents. The aim of the present research is to produce nano niosomes containing Bunium persicum essential oil with high efficiency in the temperature and acidity of the living environment of Trichomonas vaginalis parasite and to investigate its toxicity on this parasite. First, Essential oil compounds were identified using GC-Mass. Then six niosomal formulations were made using Tween 40, 60, and 80 and cholesterol by thin film method. Three formulations that have more suitable particle size, zeta potential, and essential oil release and encapsulation efficiency were selected by MTT method to investigate the toxicity on HFF (Human foreskin fibroblasts) cell line. The formulation with lower toxicity was optimized using DSPE-mPEG(2000) polymer. Encapsulation efficiency, particle size, zeta potential, release of essential oil (in temperature and acidity similar to Trichomonas vaginalis living environment), particle morphology and toxicity of optimal formulation (on HFF and Trichomonas vaginalis) were investigated. At the end, the stability of the optimized nanoparticles was studied for 120 days. 12 chemical compounds including γ-Terpinene, Cuminic aldehyde and Para-cymene were identified Bunium persicum essential oil. The optimized formulation has a particle size of 159.73 nm, a zeta potential of -25.1 mV and an encapsulation efficiency of 63.11 %, which has a slow and continuous release at the similar temperature and acidity as Trichomonas vaginalis. Niosomal nanoparticles have a spherical shape and a smooth surface and have little toxicity on the HFF cell line. Also, the toxicity of nano niosomes containing essential oil on Trichomonas vaginalis is higher than free essential oil in all concentrations. The optimized niosomal nanoparticles have good stability because their physicochemical properties have changed very little during 120 days. In conclusion optimized Niosomal formulation containing Bunium persicum essential oil compared to free essential oil can have a higher efficiency to deal with Trichomonas parasite in laboratory conditions.

Review of fish protein hydrolysates: production methods, antioxidant and antimicrobial activity and nanoencapsulation.

Marine products have gained popularity due to their valuable components, especially protein, despite generating significant waste. Protein hydrolysates are widely recognized as the most effective method for transforming these low-value raw materials into high-value products. Fish protein hydrolysate (FPH), sourced from various aquatic wastes such as bones, scales, skin, and others, is rich in protein for value-added products. However, the hydrophobic peptides have limitations like an unpleasant taste and high solubility. Microencapsulation techniques provide a scientific approach to address these limitations and safeguard bioactive peptides. This review examines current research on FPH production methods and their antioxidant and antibacterial activities. Enzymatic hydrolysis using commercial enzymes is identified as the optimal method, and the antioxidant and antibacterial properties of FPH are substantiated. Microencapsulation using nanoliposomes effectively extends the inhibitory activity and enhances antioxidant and antibacterial capacities. Nevertheless, more research is needed to mitigate the bitter taste associated with FPH and enhance sensory attributes.

New Insights in Psoriasis Management using Herbal Drug Nanocarriers.

Psoriasis (Pso) is an autoimmune inflammatory skin disease characterized by red plaques covered in silver scales. The existing treatments provide limited benefits and are associated with certain drawbacks which limit their use. Thus, there is a need to explore more options that are highly target-specific and associated with minimal side effects. Researchers have thoroughly investigated the use of herbal drugs for their therapeutic potential. Preclinical studies demonstrate that phytochemicals such as curcumin, psoralen, and dithranol have antipsoriatic effects. These phytoconstituents inhibit the signalling pathways, such as the interleukin (IL) 23/Th17 axis and IL36 inflammatory loop involved in the pathogenesis of Pso. These phytoconstituents downregulate the pro-inflammatory cytokines like IL17 and tumor necrosis factor (TNF)-α. However, their application in clinical settings is limited due to poor bioavailability and access to target sites. Combining phytoconstituents with modern delivery platforms like nanocarriers can address these shortcomings and improve therapeutic efficacy. This review explores the potential of herbal remedies as a substitute for conventional therapies, emphasizing the clinical trials conducted with these herbal medicines. The paper is supported by the discussion on nanocarriers like liposomes, niosomes, emulsomes, ethosomes, nanostructured lipid carriers, nanoemulsions, and dendrimers that are used to deliver herbal medicines.
