Zinc-substituted cytochrome c (Zn-cyt c) is noncovalently bound to single-walled carbon nanotubes (SWNTs), causing the Zn-cyt c fluorescence to be quenched by up to 95%, primarily due to photoinduced charge transfer. Deposition of Zn-cyt c/SWNT films onto conductive oxides allows for harvesting of photoexcited electrons with an internal quantum efficiency of over 5%.
