“…Ceylan et al worked on a tissue engineering application of CZTS QDs by the loading of QDs into membranes. They developed wound dressing scaffolds with antimicrobial properties by using CZTS QDs to stop wound infections, suggesting that CZTS QDs-integrated membranes have potential applications as antimicrobial layers for the purpose of wound healing [43]. Kumar et al explored the antibacterial activity of the synthesized tube-shaped CZTS NPs towards Gram-positive and Gram-negative bacteria, demonstrating that the synthesized CZTS particles exhibited strong antibacterial activity, equivalent to that of Ag NPs and ampicillin [44].…”

The importance and breadth of applications of the family of quaternary chalcogenides with the formula Cu2ZnSnSxSe(4−x) (CZTS/Se) where x = 0–4 are steadily expanding due to the tunable optoelectronic properties of these compounds and the Earth abundance of the elements in their composition. These p-type semiconductors are viewed as a viable alternative to Si, gallium arsenide, CdTe, and CIGS solar cells due to their cost effectiveness, Earth’s crust abundance, and non-toxic elements. Additionally, CZTS/Se compounds have demonstrated notable capabilities beyond solar cells, such as photoelectrochemical CO2 reduction, solar water splitting, solar seawater desalination, hydrogen production, and use as an antibacterial agent. Various routes have been explored for synthesizing pure CZTS/Se nanomaterials and significant efforts have been dedicated to reducing the occurrence of secondary phases. This review focuses on synthetic approaches for CZTS/Se nanomaterials, with emphasis on controlling the size and morphology of the nanoparticles and their recent application in solar energy harvesting and beyond, highlighting challenges in achieving the desired purity required in all these applications.

“…Chaudhari et al fabricated CZTS nanoparticles via solvothermal method and carried out the antibacterial activities of the nanoparticles in contrast to a group bacterial strain and obtained signi cant antibacterial activity using zone of inhibition [44]. In a study reported by Ceylan et al [45], hydrothermally prepared CZTS quantum dots were loaded onto PVA/chitosan membranes and the antimicrobial activity of these composite lms were examined against S. aureus and E. coli. According to the results, there is an improvement in antimicrobial properties with the contribution of CZTS.…”

Because of their acute toxicity and long-lasting effects on the environment such as chemical accidents, agricultural runoff, and industrial effluents, has raised concerns around the world. Semiconductor-based photocatalysis has gained prominence for its ability to degrade organic contaminants comprehensively, providing a potential solution to the limitations of the conventional methods. This study addresses the environmental repercussions of dye contamination and explores the utilization of active semiconductor photocatalysts for effective wastewater treatment. Our focus lies in synthesizing CZTS through the hydrothermal route, a method gaining traction for its simplicity and environmental viability. To augment the photocatalytic efficiency of semiconductor materials, graphene oxide (GO) has been introduced with varying GO concentrations of 5% and 10%. Additionally, the study explores the performance of CZTS nanoparticles with varying GO concentrations for antibacterial applications against eight Gram-positive/negative bacterial strains and its catalytic prowess in the photodegradation of methylene blue dye under ultraviolet light.

“…These additives include nanoparticles of silver, gold, copper, zinc oxides, titanium dioxide, hematite, and copper(I) iodide, quantum dots, etc. [31][32][33][34][35][36][37][38][39]. Melamine nanoparticles introduced into the chitosan matrix accelerate the healing of infected diabetic wounds due to the rapid absorption of anti-inflammatory cytokines and reactive oxygen species, the high concentration of which in diabetic patients prevents and impairs wound healing [40].…”

A silver-containing gel based on polyvinyl alcohol and aryloxycyclotriphosphazene containing β-carboxyethenylphenoxy and p-formylphenoxy groups has been developed. Phosphazene was synthesized via the Doebner reaction from hexakis[(4-formyl)phenoxy]cyclotriphosphazene and malonic acid and characterized by 1H, 13C, and 31P NMR spectroscopy and MALDI-TOF mass spectrometry. The study of the gel using scanning electron microscopy showed that the gel contains open pores and can absorb wound exudate. The maximum water absorption capacity of the gel was 272%, which was reached after 80 min of testing. The antimicrobial activity of the obtained silver-containing gel was evaluated using the diffusion method. The gel was found to inhibit the growth of the main microorganisms in contact with the skin: the bacteria S. aureus, P. aeruginosa, E. coli, B. subtilis, S. epidermidis, and C. stationis and the fungus C. albicans. The study of the wound-healing effect of the gel in vivo showed a decrease in the wound area of the rabbit hind limb by 91.43% (p < 0.05) on the 10th day of observation and a decrease in the content of C-reactive protein in the rabbit blood serum by 1.3 times (p < 0.05).
