Biosynthesis of Silver Nanoparticles and their Antimicrobial Properties: A Review on Recent Advances

Abstract

Today, the world is witnessing the rapid advancement of nanotechnology in our everyday life, with numerous applications in energy, medicine, food, water, cosmetics and pharmaceuticals. Synthesis of silver nanoparticle is critical since their use is highly dependent on their form, size, and dispersion. The search for synthetic technologies which are safe for humans and the environment prompted researchers to employ locally accessible biogenic ingredients for silver nanoparticles. silver nanoparticles (AgNPs) are now employed as antimicrobial agents and produced using diverse procedures. This review article reports the green techniques for the synthesis of silver nanoparticles, which are eco-friendly, sustainable and energy-efficient that cause little pollution and pose no health risks. The goal of this article is to highlight and review the application of green synthesis methods that employ biological entities, specifically plants and microorganisms (bacteria, fungus and algae), for the formation of silver nanoparticles and their antimicrobial effect with an emphasis on research done in the previous five years.
