Biosynthesis and Antimicrobial Potential of Metal Nanoparticles.

One of the major developments in nanotechnology is the production, manipulation, and use of materials ranging in size from less than a micrometer to that of individual atoms in biology. Though nanomaterials may be synthesized by various physical and chemical methods, synthesis is now possible with the use of biological systems. Nanoparticles synthesized using biological resources have excellent antimicrobial activity. In this review, we critically assess the role of biological entities in the synthesis and antimicrobial potential of metal nanoparticles. [ABSTRACT FROM AUTHOR]
