Short peptide mediated self-assembly of platinum nanocrystals with selective spreading property

Abstract

Spherical assemblies with core/shell configurations are prepared through C-terminal amidated short peptide mediated self-association of platinum nanocrystals. The interactions between the peptides might drive the self-assembly of platinum nanocrystals and determine their surface properties. Thus, the nanosize assemblies collapse and spread on a hydrophilic surface, whereas maintaining their spherical shapes on a hydrophobic surface.
