Zusammenfassung:Please release me: Hydrocarbon monolayers attached to a TiO2 surface can be cut by electrochemical means, thus allowing active molecules or proteins to be released from the TiO2 surface (see picture). Requirements are suitable electronic properties of TiO2 combined with a voltage to cause Schottky barrier breakdown; valence band holes are then sufficiently reactive to generate OH. radicals.
