Abstract

Studies of silver nanoparticle formation using MWNT-protein/polypeptide conjugates are reported. Our findings suggest that there is selectivity in the formation of silver nanoparticles depending on the nature of the protein. Protein-mediated mineralization is facile and can be carried out under mild conditions, thereby enabling retention of the biological activity of the protein.
