A Review on Green Synthesis and Antibacterial Activity of Silver Nanoparticles

摘要

Nanotechnology is a broad interdisciplinary field of science that represents the design, synthesis, characterization and application of materials at nano scale level. Nanoparticles (NPs) are viewed as fundamental building blocks of nanotechnology. The term “nano scale” is generally referred to a scale between 1-100 nm. Nowadays, synthesis of NPs has been the subject of a lot of studies due to its commercial demands and wide applicability in various fields such as chemistry, biology, physics, material science, engineering, medicine etc. Silver nanoparticles (AgNPs) can be synthesized using chemical methods, physical methods, and biological methods. Green synthesis of AgNPs is efficient, fast, cheap, non-toxic, simple and eco-friendly than commonly used physicochemical methods. Green chemistry processes led to eco-friendly method of synthesis and safe process as compared to other methods. In this review, a cheap and environment friendly technique for synthesis of AgNPs by green chemistry approach was explained. Also antibacterial activity of AgNPs has been reviewed.
