Biosynthesis of silver nano-particles by the bacterium micrococcus luteus.

ABSTRACT

Nanotechnology is the application of science to control matter at the molecular level. It is a field that is burgeoning in the recent times, making an impact in all spheres of human life. Microorganisms play an important role in the eco-friendly synthesis of metal nanoparticles. The use of microorganisms for the synthesis of nanoparticles in the lime light of modern nanotechnology is a novel approach. Biological methods of synthesis have paved the way for the greener synthesis of these nanoparticles which can have application in biomedical sciences. In this study, we report the synthesis of nanoparticles of silver by the reduction of aqueous Ag+ by a culture of Micrococcus luteus. The formation of silver nano-particles was monitored by X-ray diffraction spectroscopy (XRD) and elucidated by transmission electron microscopy (TEM).
