Peptide modification on the interior surface of red blood cell ghosts for construction of catalytic reactors†
Abstract
We have succeeded in in situ synthesis of gold nanoparticles (Au NPs) on the interior surfaces of red blood cell ghosts (RBCGs) with a cytoskeleton chemically conjugated to a gold-binding peptide. The Au NP-deposited RBCG with the peptide exhibits enhanced catalytic reactivity for the reduction of 4-nitrophenol due to the uniform distribution of the Au NPs on the inner surface and the coverage of the Au NPs surface with the peptide.
