摘要：
Amyloid-like fibrils have been obtained upon incubation of a diluted aqueous solution of cytochrome c at neutral pH in the presence of gold nanoparticles. The interaction of the cytochrome c suspension, containing proteins in both the monomeric and fibrillar state, with the freshly cleaved highly ordered pyrolytic graphite (HOPG) surface results in a double process. First, it leads to a nanopatterning of the HOPG surface and, second, it promotes the self-aligning of cytochrome c protofilaments on the nanopatterned HOPG surface. © Springer Science+Business Media, LLC 2012.
