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.

Summary

Introduction

Nanoparticles and nanocomposites are employed in a variety of applications across a wide range of industries. Plant extracts can be used to make silver nanoparticles that are both environmentally friendly and costeffective [2] Plant extracts such as Boerhavia diffusa leaves [3], Piper nigrum stem and leaf [4], Avicennia marina mangrove plant [5], Cissus quadrangularis [6], Parthenium hysterophorus [7], Manilkara zapota seeds [6], and Chrysanthemum flower extracts [8] and fruit extracts of pomegranate [9], Dillenia indica [10], Solanum xanthocarpum [11], and Crataegus douglasii [12] were employed, and it was used for antibacterial, antifungal, and antioxidant properties. Chitosan-based silver nanocomposites, which include chitosan with silver nanoparticles, are being developed for a variety of commercial uses. We employed citrus lemon juice to synthesize chitosan-based silver nanocomposites (CS-Ag nanocomposite). Antioxidant and antibacterial activity against fungal infections is performed to the nanocomposites which have been synthesized
