Biosynthesis of Silver Nanoparticles from various Microbial and Green resources-A Review

One of the advanced techniques of material science is nanotechnology which includes the small sized nanoparticles that exhibit enhanced properties as compared to the bulk material. Due to the extremely small size, nanoparticles have large surface area relative to their volume. Wide range of biological systems ranging from bacteria to plants and mammals can be used for synthesizing nano-sized particles of interest in order to develop clean, non-toxic and eco-friendly technologies. Biological molecules as reducing agents and oxidizing agents are significantly safe over their chemical counterparts thus obviating the need of chemical reagents for synthesis. It has also become necessary to explore the properties of nanorugs due to the reason that microbes are abruptly gaining resistance against the wide range of present day antibiotics. Silver nanoparticles are being more attracted due to their therapeutic, bimolecular, detection and catalysis applications. Nanotechnology is a rapidly growing field with significant applications in various areas including the synthesis and applications of nano-materials. The present review explores the huge microbial and plant diversity to be utilized towards rapid and single step protocol preparatory method.
