| Research Abstract |
This work was carried out to develop a new methodology for constructing highly programmed hierarchical nanostructures with self-assembly of complementary peptides bearing nucleobase moieties as complementary recognition parts. As a result, we found that the self-assembly of platinum-complex-bound amino acid derivative self-assemble to afford a supramolecular fibril aggregate constructed of 1-D arrayed platinum nanostructures. The programmed self-assembly also enabled us to fabricate large-area gold nanoparticle 2-D array whose optical and catalytic properties have been studied.
