S. Rajeshkumar
Abstract
Nanoparticles are important advanced materials with numerous uses in a variety of fields. Novel antibacterial nanocomposites with synergistic capabilities can be created by combining metal nanoparticles with biopolymers of various functionalities. This research evaluates an antimicrobial and antioxidant-rich chitosan-based silver nanocomposite synthesized by using citrus lemon extract as a reducing and capping agent. UV-vis spectrophotometer, scanning electron microscope, elemental dispersive analysis, X-ray diffraction assay, atomic force microscope, Fourier transform infrared spectroscopy, UV-near infrared spectroscopy, and transmission electron microscopy were used to characterize the chitosan-based silver nanocomposite (CS-Ag nanocomposite). The nanocomposite synthesized is used to demonstrate antioxidant and antimicrobial activity against fungal pathogens.
