Abstract: The present invention is a monolithic photoelectrochemical cell for photoelectrical-induction of a chemical reaction and a method capable of vectorial electron transfer apparatus including one or more semiconductor electrodes and one or more dye sensitized electrodes positioned in communication with an electrolyte whereby the electrode is capable of vectorial electron transfer upon exposure to electromagnetic radiation.

Abstract: Described herein is an apparatus comprising an electrochemical cell that employs a capacitive counter electrode and a faradaic working electrode. The capacitive counter electrode reduces the amount of redox products generated at the counter electrode while enabling the working electrode to generate redox products. The electrochemical cell is useful for controlling the redox products generated and/or the timing of the redox product generation. The electrochemical cell is useful in assay methods, including those using electrochemiluminescence. The electrochemical cell can be combined with additional hardware to form instrumentation for assay methods.

Abstract: A modular reactor system and method for synthesizing nanoscale quantities of chemical compounds characterized by a continuous flow reactor under high pressure having uniform temperature throughout the reaction mixture. The apparatus includes a number of generic components such as pumps, flow channels, manifolds, flow restrictors, valves and at least one modular reactor, as small as one nanoliter in volume, where larger quantities can be produced by either using larger nanoscale sized units or adding parallel and serially disposed nanoscale reactor units.
