Abstract: A method of testing a liquid sample for the presence of an analyte, the method comprising the steps of: forming a mixture by contacting the sample with a composition comprising an oxidase for formation of hydrogen peroxide from the analyte, a fluorescent indicator precursor capable of forming a fluorescent indicator in the presence of an oxygen radical and an iron compound wherein the iron compound is dissolved in the mixture; irradiating the mixture; and measuring fluorescence from the fluorescent indicator. The method may be carried out using a device in which the mixture in a channel or chamber (101) of a microfluidic device is irradiated by light from light source (103) and emission from the fluorescent indicator is detected by photodetector (105).

Abstract: The present invention relates to an organic flow cell battery having a material comprising an organic molecule that can be used as the electroactive redox material for both electrodes of the battery. By enabling two-electron processes both of the oxidation and reduction to occur in a single molecule, a total of 4-electron transitions is achieved, which allows the organic molecule to be used on both sides of the separator, reducing material costs and allowing the battery to be charge in either direction with equal ease.
