A facile strategy is used to synthesize the gold nanoparticles via a green and simple approach showing self-alignment on the assembled nanofibers of ultrashort oligopeptides as a composite material. A photochemical reduction method is used, without requiring any external chemical reagents for the reduction of gold ions and producing gold nanoparticles of size ca. 5 nm under mild UV light exposure. The specific arrangement of gold nanoparticles on peptide nanofibers may indicate electrostatic interactions of two components and interactions with the amino group of the peptide building block. The gold-peptide nanoparticle composites show the ability as a catalyst to degradation of environmental pollutant p-nitrophenol to p-aminophenol, and the reaction rate constant for catalysis is 0.057 min−1 at a 50-fold dilute sample of 2 mg/mL and 0.72 mM gold concentration in the composites. This colloidal strategy helps researchers to fabricate the metalized bioorganic composites for biomedical and bio-catalysis applications.
