Green synthesis of zinc nano particle by microbes

Abstract

Nanoparticles can be synthesized by using microbes and by plant extracts. Under the favorable conditions, size and surface of nanoparticles can be easily altered to achieve both passive and active transportation of drug. It can be projected forthe specific sites by attaching ligands to nanoparticle surface. Nanotechnology is recognized as the study of particle with a minimum of one dimension in nanometers. Synthesis of nanoparticles can be done through three methods like physical, chemical, and green synthesis methods. Green synthesis can be done using microorganisms, enzymes, or plant extracts. This project work is based and focused on the green synthesis method due to its non-toxic and ecofriendly process. In this project, Zinc (II) ion solution is reduced into ZnO nanoparticles using microbes like Bacillus thuringenesis and Bacillus species. Characterization of Zinc nanoparticles was done by UV-Visible spectrophotometer for its Surface Plasmon resonance, SEM for morphologies, XRD and FTIR for its crystalline nature.
