Formation of Au/Pd Alloy Nanoparticles on TMV

Formation of Au/Pd Alloy Nanoparticles on TMV

A gold-palladium (AuPd) solid solution alloy was successfully deposited on the genetically engineered tobacco mosaic virus (TMV1Cys) by the biosorption of Au(III) and Pd(II) precursors and the reduction of the Au(III) and Pd(II) to their respective metals or metal alloy. The resulting morphologies o...
