Biosynthesis of Au, Ag and Au–Ag bimetallic nanoparticles using protein extracts of <em>Deinococcus radiodurans</em> and evaluation of their cytotoxicity

Abstract

These results are crucial to understand the biosynthetic mechanism and properties of noble metallic NPs using the protein extracts of bacteria. The biocompatible Au or Au-Ag bimetallic NPs are applicable in biosensing, bioimaging and biomedicine.
