A COMPREHENSIVE REVIEW OF GREEN SILVER NANOPARTICLE SYNTHESIS VIA MEDICINAL PLANTS

Abstract

One sustainable and green approach to synthesizing nanoparticles is the green synthesis of silver nanoparticles (AgNPs) using medicinal plant extracts. This research mainly deals with the synthesis of AgNPs by using aqueous plant extracts as reducing, stabilizing, and capping agents. Nanotechnology, an emerging field of biomedical science, has been a key driver of various technological developments since its advent in the 21st century. The combination of nanotechnology and biotechnology has resulted in an expanding interdisciplinary area that bridges materials science, nanotech, and biology. Known as "bio-nanotechnology" as a whole, this area investigates the numerous applications of nanoparticles in medicine. For the examination of the size, shape, and crystal structure of the developed nanoparticles, scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) methods were used. Although the prefix "nano" is derived from the Greek word for "dwarf," most nanoparticles are usually between one and five hundred nanometers in size. Their precision in delivering drugs—into the right place, at the right time, and in the right dose—has put nanoparticles at the center of drug delivery research.
