Please release me : Hydrocarbon monolayers attached to a TiO 2 surface can be cut by electrochemical means, thus allowing active molecules or proteins to be released from the TiO 2 surface (see picture). Requirements are suitable electronic properties of TiO 2 combined with a voltage to cause Schottky barrier breakdown; valence band holes are then sufficiently reactive to generate OH . radicals.
