    Abstract: A modifying agent for a conductive substrate comprises a flavin derivative. A flavin-modified electrode obtained through modification by the modifying agent is capable of reducing an electron transfer protein having a standard oxidation-reduction potential higher than, or on the positive side of, the standard oxidation-reduction potential of the flavin derivative but is incapable of oxidizing the electron transfer protein, and is therefor capable of controlling electron transport so that the electron transport takes place in only one direction. With this characteristic feature, the modified electrode is applicable to functional devices such as diodes, transistors and optical switch devices.
