Abstract

Pass it on! Highly conductive silver nanoparticles (NPs; see picture) act as efficient electron relays on a pyrolytic graphite (PG) electrode, and heavily negatively charged silver NPs provide suitable docking sites for positively charged cytochrome c (cyt c). Direct, well-defined electrochemistry of cyt c is obtained at an assembled silver NPs/PG electrode surface, which results in an electron-transfer rate of 15.8 s^-1 for cyt c. The usage of silver NPs will open new opportunities for studying in vitro electron-transfer processes of heme protein and for fabrication of bioelectronic devices.
