Assemblies of metal nanoparticles and self-assembled peptide fibrils - Formation of double helical and single-chain arrays of metal nanoparticles

Double helical and single-chain arrays of Au and Pd metal nanoclusters; have been achieved by assembling the corresponding metal nanoparticles on peptide nanofibril templates at different pH values. The assembled metal nanoparticles are useful for studying the superstructures of the peptide nanofibrils. Pd nanowires of different shapes have also been prepared by varying the amount of metal deposition.
