Photoresponsive electrode for determination of redox potential

Abstract From the Canadian patent

Device and methods are provided for determining the presence and amount of an analyte by measuring a redox potential-modulated photoinducing signal from a photoresponsive element. Further devices and method are provided for determining the presence and amount of an analyte by measuring a redox potential, pH or ion modulated photoinduced signal from a photoresponsive element, where one signal is a constant system and the other signal(s) is a variable system The constant system signal is used to standardize the variable system signal. Various protocols may be employed where an analyte may be directly or indirectly coupled to a redox couple a pH, or ion system for detection. The latter devices …
