Abstract

The conjugation of organic molecules to matal nanoparticles has been of much interest due to direct organization into larger supramolecular structures by self-assembly. In this report, we demonstrate formation of composite material from single crystals of L-cystine and Au nanoparticles. Particularly, SEM, AFM, UV-Vis spectroscopy indicated that the (001) surface of L-cystine single crystals was coated selectively by Au nanoparticles. X-ray crystallographic study revealed that the disulfide moieties or amino acid groups are arranged in 2D fashion on (001) face. This provides the selective coating of Au nanoparticles.
