Abstract
A study was conducted to explore the potential of using chitosan (CS) derived from shrimp shells, a bioorganic waste product, as a reducing and capping agent in the synthesis of silver nanocomposites (Cs-Ag NC). The objective of the study was to develop a simpler, faster, and more environmentally friendly method for producing Cs-Ag NC. The synthesized Cs-Ag NC was characterized using UV-Vis spectroscopy, X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, and scanning electron microscopy. The findings revealed that the Cs-Ag NC exhibited a crystalline structure, was coated with CS components, and had a spherical shape with an average diameter of approximately 20 nm. Under optimal conditions, the synthesized Cs-Ag NC demonstrated significant free radical scavenging activity against 2-diphenyl-1-picrylhydrazyl (DPPH) with an IC50 value of 1.65 mg/mL, substantial free radical scavenging activity against 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) with an IC50 value of 2.8 mg/mL, and notable anti-inflammatory activity. Additionally, the Cs-Ag NC exhibited significant antibacterial activity against several pathogenic strains, including Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus. Based on these findings, the synthesized Cs-Ag NC possess promising potential as therapeutic drugs for antioxidant and antibacterial applications.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
