The futuristic applications of transition metal dichalcogenides for cancer therapy.

The second-most common cause of death resulting from genetic mutations in DNA sequences is cancer. The difficulty in the field of anticancer research is the application of the traditional methods, which also affects normal cells. Mutations, genetic replication alterations, and chromosomal abnormalities have a direct impact on the effectiveness of anticancer drugs at different stages. Presently, therapeutic techniques utilize nanotechnology, transition metal dichalcogenides (TMDCs), and robotics. TMDCs are being increasingly employed in tumor therapy and biosensing applications due to their biocompatibility, adjustable bandgap, versatile functionality, exceptional photoelectric properties, and wide range of applications. This study reports the advancement of nanoplatforms based on TMDCs that are specifically engineered for responsive and intelligent cancer therapy. This article offers a thorough examination of the current challenges, future possibilities for theranostic applications using TMDCs, and recent progress in employing TMDCs for cancer therapy. Currently, there is significant interest in two-dimensional (2D) TMDCs nanomaterials as ultrathin unique physicochemical properties. These materials have attracted attention in various fields, including biomedicine. Due to their inherent ability to absorb near-infrared light and their exceptionally large surface area, significant efforts are being made to prepare multifunctional nanoplatforms based on 2D TMDCs.

Mechanism and potentialities of photothermal and photodynamic therapy of transition metal dichalcogenides (TMDCs) against cancer.

The ultimate goal of nanoparticle-based phototherapy is to suppress tumor growth. Photothermal therapy (PTT) and photothermal photodynamic therapy (PDT) are two types of physicochemical therapy that use light radiation with multiple wavelength ranges in the near-infrared to treat cancer. When a laser is pointed at tissue, photons are taken in the intercellular and intracellular regions, converting photon energy to heat. It has attracted much interest and research in recent years. The advent of transition materials dichalcogenides (TMDCs) is a revolutionary step in PDT/PTT-based cancer therapy. The TMDCs is a multilayer 2D nano-composite. TMDCs contain three atomic layers in which two chalcogens squash in the transition metal. The chalcogen atoms are highly reactive, and the surface characteristics of TMDCs help them to target deep cancer cells. They absorb Near Infrared (NIR), which kills deep cancer cells. In this review, we have discussed the history and mechanism of PDT/PTT and the use of TMDCs and nanoparticle-based systems, which have been practiced for theranostics purposes. We have also discussed PDT/PTT combined with immunotherapy, in which the cancer cell apoptosis is done by activating the immune cells, such as CD8+.

Modulation of terpenoid indole alkaloid pathway via elicitation with phytosynthesized silver nanoparticles for the enhancement of ajmalicine, a pharmaceutically important alkaloid.

MAIN CONCLUSION: The use of silver nanoparticles as elicitors in cell cultures of Rauwolfia serpentina resulted in increased levels of ajmalicine, upregulated structural and regulatory genes, elevated MDA content, and reduced activity of antioxidant enzymes. These findings hold potential for developing a cost-effective method for commercial ajmalicine production. Plants possess an intrinsic ability to detect various stress signals, prompting the activation of defense mechanisms through the reprogramming of metabolites to counter adverse conditions. The current study aims to propose an optimized bioprocess for enhancing the content of ajmalicine in Rauwolfia serpentina callus through elicitation with phytosynthesized silver nanoparticles. Initially, callus lines exhibiting elevated ajmalicine content were established. Following this, a protocol for the phytosynthesis of silver nanoparticles using seed extract from Rauwolfia serpentina was successfully standardized. The physicochemical attributes of the silver nanoparticles were identified, including their spherical shape, size ranging from 6.7 to 28.8 nm in diameter, and the presence of reducing-capping groups such as amino, carbonyl, and amide. Further, the findings indicated that the presence of 2.5 mg L-1 phytosynthesized silver nanoparticles in the culture medium increased the ajmalicine content. Concurrently, structural genes (TDC, SLS, STR, SGD, G10H) and regulatory gene (ORCA3) associated with the ajmalicine biosynthetic pathway were observed to be upregulated. A notable increase in MDA content and a decrease in the activities of antioxidant enzymes were observed. A notable increase in MDA content and a decrease in the activities of antioxidant enzymes were also observed. Our results strongly recommend the augmentation of ajmalicine content in the callus culture of R. serpentina through supplementation with silver nanoparticles, a potential avenue for developing a cost-effective process for the commercial production of ajmalicine.

Several RNA aptamers with potential implications in cancer diagnosis are known to confer a great affinity for single-stranded DNA molecules, long non-coding RNAs, circulating tumor cells, vascular endothelial growth factors, and tissue and sera-derived exosomes in patients with different malignancies. Furthermore, clinical investigations have revealed the efficacy of RNA aptamer-based agents in imaging modalities. This review seeks to deliver new insights into the development, classification, nanomerization, and modification of RNA aptamers, as well as their applications in cancer theranostics. The aptamers' mechanism of action and their interest to clinical trials as theranostic agents are also discussed.

Recent developments of polysaccharide based superabsorbent nanocomposite for organic dye contamination removal from wastewater - A review.

One of the main problems with water pollution is dye contamination of rivers, industrial effluents, and water sources. It has endangered the world's sources of drinking water. Several remediation strategies have been carefully developed and tested to minimize this ominous picture. Due to their appealing practical and financial benefits, adsorption methods in particular are often listed as one of the most popular solutions to remediate dye-contaminated water. Biopolymer-based hydrogel nanocomposites are a cutting-edge class of materials with a wide range of applications that are effective in removing organic dyes from the environment.

Luminescence nanomaterials for biosensing applications.

Due to their capacity to immobilize more bioreceptor parts at reduced volumes, nanomaterials have emerged as potential tools for increasing the sensitivity to specific molecules. Furthermore, carbon nanotubes, gold nanoparticles, polymer nanoparticles, semiconductor quantum dots, nanodiamonds, and graphene are among the nanomaterials that are under investigation. Due to the fast development of this field of research, this review summarizes the classification of biosensors using the main receptors and design of biosensors.

Locust Bean gum-based hydrogels embedded magnetic iron oxide nanoparticles nanocomposite: Advanced materials for environmental and energy applications.

This paper reports a simple method of designing and synthesizing magnetic iron oxide (IO) integrated locust bean gum-cl-polyacrylonitrile hydrogel nanocomposites (LBG-cl-PAN/IONP) by in situ mineralization of iron ions in a hydrogel matrix. A two-step gel crosslink method followed by co-precipitation method was used to prepare these novel hydrogels embedded with magnetic iron oxide nanoparticles. The LBG-cl-PAN/IONP hydrogel nanocomposite (HNC) were tested in batch adsorption experiments for their ability to remove a cationic dyes, methylene blue (MB) & Methyl violet (MV), from aqueous solution. In order to analyze the LBG-cl-PAN/IONP HNC, FTIR, XRD, XPS, VSM, TEM, and EDX techniques were applied. Numerous operating parameters were studied, including the amount of adsorbent, the contact time, pH, temperature, the dye concentration, and the coexisting ion concentration. According to the Langmuir isotherm model, MB and MV had maximum monolayer adsorptive capacities of 1250 and 1111 mg/g, respectively. LBG-cl-PAN/IONP HNC controlled IONP oxidation as well as sustained adsorptive removal over a wide pH range (7-10). The key mechanism of adsorption consisted of electrostatic interaction and ion exchange. For successful use in successive cycles after regeneration using HNO3 as eluent, the LBG-cl-PAN/IONP HNC can easily be reused. As a material, the LBG-cl-PAN/IONP HNC is a promising sorbent or composite material for removing toxic dyes from water, and therefore can be applied to enhance water and wastewater treatment technology. Additionally, we have briefly evaluated LBG-cl-PAN/IONP HNC for antibacterial and supercapacitor applications. According to our knowledge, this is the first report describing the use of LBG-cl-PAN/IONP HNC multifunctional efficacy as an excellent sorbent, antibacterial and electrochemical supercapacitor applications.

Emerging remediation potentiality of struvite developed from municipal wastewater for the treatment of acid mine drainage.

The valorisation of wastewaters for minerals recovery and their potential beneficiation has gained enormous attention recently. In this study the removal of phosphate and ammonia from municipal wastewater using activated magnesite resulted in the formation of struvite. The optimum conditions for the synthesis of struvite were 60 min of mixing, 300 rpm mixing speed, 1 g of activated magnesite and room temperature, whilst optimum conditions for the treatment of acid mine drainage (AMD) using the synthesized struvite were 45 min of mixing, 20 g of struvite dosage, 1000 mL, and 300 rpm mixing speed. The efficacy of struvite for neutralisation of AMD and attenuation of inorganic contaminants were ≥98.99% for metals (Al3+, Fe3+, and Mn2+) and ≥30% for SO42-. Traces of other metals such as Zn, Cu, Ni, Pb, and Cr were significantly attenuated. Phosphate was fully attenuated from the aqua-sphere. PHREEQC predicted the removal of minerals as oxy-(hydro)-sulphates, oxy-(hydro)-phosphate, metals hydroxides, and other complexes. FE-SEM equipped with FIB and an EDX, XRD, XRF, and FTIR confirmed the synthesis of struvite and fate of chemical species after treatment. This study confirmed the feasibility of recovering phosphate and ammonia as struvite which can be employed for the treatment of AMD.

Potassium-induced partial inhibition of lactoperoxidase: structure of the complex of lactoperoxidase with potassium ion at 2.20 Å resolution.

Lactoperoxidase, a heme-containing glycoprotein, catalyzes the oxidation of thiocyanate by hydrogen peroxide into hypothiocyanite which acts as an antibacterial agent. The prosthetic heme moiety is attached to the protein through two ester linkages via Glu258 and Asp108. In lactoperoxidase, the substrate-binding site is formed on the distal heme side. To study the effect of physiologically important potassium ion on the structure and function of lactoperoxidase, the fresh protein samples were isolated from yak (Bos grunniens) colostrum and purified to homogeneity. The biochemical studies with potassium fluoride showed a significant reduction in the catalytic activity. Lactoperoxidase was crystallized using 200 mM ammonium nitrate and 20% PEG-3350 at pH 6.0. The crystals of LPO were soaked in the solution of potassium fluoride and used for the X-ray intensity data collection. Structure determination at 2.20 Å resolution revealed the presence of a potassium ion in the distal heme cavity. Structure determination further revealed that the propionic chain attached to pyrrole ring C of the heme moiety, was disordered into two components each having an occupancy of 0.5. One component occupied a position similar to the normally observed position of propionic chain while the second component was found in the distal heme cavity. The potassium ion in the distal heme cavity formed five coordinate bonds with two oxygen atoms of propionic moiety, Nε2 atom of His109 and two oxygen atoms of water molecules. The presence of potassium ion in the distal heme cavity hampered the catalytic activity of lactoperoxidase.

Enhanced delivery of doxorubicin for breast cancer treatment using pH-sensitive starch/PVA/g-C3N4 hydrogel.

This study introduces a starch/PVA/g-C3N4 nanocarrier hydrogel for pH-sensitive DOX delivery in breast cancer. DOX was loaded into the nanocarrier with 44.75 % loading efficiency and 88 % Entrapment Efficiency. The release of DOX from the starch/PVA/g-C3N4 hydrogel was pH-sensitive: DOX was released faster in the acidic environment pertinent to cancer tumors (with a pH level of 5.4) than in the surrounding regular tissue environment carrying a more neutral environment (pH 7.4). The release kinetics analysis, encompassing zero-order, first-order, Higuchi, and Korsmeyer-Peppas models, revealed significant fitting with the Higuchi model at both pH 5.4 (R2 = 0.99, K = 9.89) and pH 7.4 (R2 = 0.99, K = 5.70) levels. Finally, we found that hydrogel was less damaging to healthy cells and more specific to apoptotic cells than the drug's free form. The starch/PVA/g-C3N4 hydrogel had low toxicity for both normal cells and breast cancer cells, whereas DOX loaded into the starch/PVA/g-C3N4 hydrogel had higher toxicity for cancer cells than the DOX-only control samples, and led to specific high apoptosis for cancer cells. The study suggests that DOX can be loaded into a starch/PVA/g-C3N4 hydrogel to improve the specificity of the drug's release in cancer tumors or in vitro breast cancer cells.

Regulation of the P53 tumor suppressor gene and the Mcl-2 oncogene expression by an active herbal component delivered through a smart thermo-pH-sensitive PLGA carrier to improve Osteosarcoma treatment.

Osteosarcoma (OS), a lethal malignancy, has witnessed an escalating incidence rate. Contemporary therapeutic strategies for this cancer have proven to be inadequate, primarily due to their extensive side effects and the lack of specificity in targeting the molecular pathways implicated in this disease. Consequently, this project is aimed to manufacture and characterize Poly (Lactic-co-glycolic acid) embodying curcumin, a phytocompound devoid of adverse effects which not only exerts an anti-neoplastic influence but also significantly modulates the genetic pathways associated with this malignancy. In this investigation, multiple formulations of PLGA-Cur were synthesized, and the choice of optimal formula was made considering the efficiency of nanoparticle encapsulation and the drug dispersion rate from synthesized PLGA. The selected formulation's physical and chemical attributes, such as its dimension, polydispersity index of the formulation, surface electrical charge, physical-spatial structure, and stability, were examined using methods, including Dynamic light scattering (DLS), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and spectrophotometry. Subsequently, the absence of interaction between the drug and the system was assessed using Fourier Transform Infrared Spectroscopy (FT-IR), and cellular uptake was evaluated using fluorescence microscopy. The smart system's responsiveness to environmental stimuli was determined using the dialysis bag method and its anti-tumor properties were investigated on the SAOS-2 cell line. Finally, to evaluate the system's genetic impact on bone cancer, the molecular quantification of the P53 tumor suppressor gene and the oncogene MCL-2 was analyzed using real-time PCR and their protein expression levels were also examined. The PLGAs synthesized in this study exhibited an encapsulation rate of 91.5 ± 1.16% and a maximum release rate of 71 ± 1%, which were responsive to various stimuli. The size of the PLGAs was 12.5 ± 321.2 nm, with an electric charge of -38.9 ± 2.6 mV and a PDI of 0.107, indicating suitable morphology and stability. Furthermore, both the system and the drug retained their natural properties after inoculation. The system was readily absorbed by cancer cells and effectively exerted its anti-cancer properties. Notably, the system had a significant impact on the mentioned genes' expression. The produced nanosystem, possessing optimal physicochemical properties, has the potential to enhance the anti-cancer efficacy of curcumin. This is achieved by altering molecular and genetic pathways within cancer cells, thereby positioning it as a viable adjunctive treatment modality and also synthesizing of this herbal base drug system consider as a completely novel method for cancer therapy that can efficiently modulate genetical pathways involved.

The present work describes the synthesis of a cellulose and gelatin based hydrogel by the grafting of poly(acrylic acid) using ammonium persulphate (APS)-glutaraldehyde as the initiator-crosslinker system. The structure of the hydrogel was studied through scanning electron microscopy (SEM) and FTIR. The maximum swelling rate of C-G-g-poly(AA) was found to be 92 g g-1 at pH 10. The size and structure of the prepared silver nanoparticles (AgNPs) were studied through TEM and zeta potential, and it was found that the synthesized AgNPs were spherical and the size range was 11-30 nm. The reduction process followed pseudo 1st order kinetics. EtBr and eosin dye degradation were more than 4 times faster, when AgNPs were used with sodium borohydride. Thus, it can be concluded that the synthesized C-G-g-poly(AA) AgNPs hybrid hydrogel is effective for the reduction and degradation of carcinogenic dyes in wastewater.
