“…Using a Butler-Volmer kinetic model to fit the data, a k 0 of 1.35 s À1 was determined. [21][22][23] Although faster rates have been reported with planar electrodes (18 s À1 on ITO), 24 this rate is comparable to that determined for cytC adsorbed to other mesoporous materials like SnO 2 or porous ITO. 10,14 Owing to the excellent transparency of the porous ATO films, the characteristic UV-vis spectrum of oxidized cytC including both the Soret band (409 nm) and the Q-band (circa 530 nm) could be easily detected through the coated slide in an ordinary transmission mode experiment without any signal amplification (Fig.…”
Stable immobilization of two redox proteins, cytochrome c and azurin, in a thin film of highly mesoporous antimony-doped tin oxide is demonstrated via UV-vis spectroscopic and electrochemical investigation.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
