Biosynthesis of Nanoparticles : Revi

Abstract

Nanotechnology can be defined as the characterization, exploration and application of nanosized (1-100nm) materials for the development of science. Though chemical methods continue to be analyzed for the shape and size controlled synthesis of metal nanoparticles, they can be nocuous to the environment due to the use of toxic chemicals. Research erstwhile has demonstrated that utilization of biological organisms majorly microorganisms has been emerging as a novel and unique method for the synthesis metal nanoparticles(NP), which can be preferred over the existing chemical and physical methods. Keywords: Microorganisms, metal nanoparticles, nanoparticles, synthesis
