Peptide building blocks have biocompatibility, biological recognition abilities, and chemical versatility, and they can be easily synthesized. Therefore, many researchers have studied about using peptide to make nanostructures having various functional abilities. Peptide self-assembly process is important to regulate various functions such as bio-mineralization and catalytic activity. Recently, we have reported that series of tyrosine-rich peptides (TRPs) induced nano film formation at air-water interface and played a critical role as a catalytic scaffold. Here, through interactions between TRPs and metal ions, we have found that both peptide assembly and the formation of metal nanoparticles (NPs) can be easily manipulated. Especially, we have noticed that TRPs could induce the reduction of palladium (II) ion to Pd NPs (5-6 nm). The folding and conformational change of the peptides with Pd+2 ions made the Pd NPs to form a raspberry-like structure. Additionally, these raspberry-shaped Pd NPs showed good catalytic activities in copper-free Sonogashira cross-coupling reaction in water.
