GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES FOR ENHANCED ANTIBACTERIAL APPLICATIONS

Abstract

Physicochemical properties and strong antibacterial activity, Silver nanoparticles (AgNPs) are very popular. Conventional approaches to the production of nanoparticles often entail the use of toxic chemicals, producing industrial waste and harmful by-products, which are a threat to health and the environment. The so-called green synthesis, which relies on such methods of reduction that use (eco)biological resources such as extracts of higher plants, microorganisms, and natural biomolecules, is more easily reproducible, cheaper, and more environmentally friendly. In this study, Silver nanoparticles were produced using the green synthesis method, and a range of characterization methods were used to study the morphology and physicochemical properties of the nanoparticles. In addition, UV-Visible spectra, Fourier Transform Infrared spectra (FT-IR), X-Ray Diffraction (XRD) and electron microscopy were used to assess the formation of nanoparticles, functional groups, crystallinity, and morphology of the particles. The antibacterial activity of the produced silver nanoparticles was also tested, and the obtained results showed a positive outcome, which predicts the widespread use of green synthesized AgNPs in biomedicine, health care products, food packaging, and environmental protection. Sustainable synthesis of nanoparticles remains important for developing better antibacterial agents.
