First Claim
Patent Images
1. A photoresponsive device for making a plurality of determinations of a redox substance capable of modifying an electrical signal resulting from irradiation of a photoresponsive element, said device comprising:
- a photoresponsive element having an irradiation receiving surface;
irradiation means for irradiating said surface;
a counterelectrode;
means for polarizing said element with respect to said counterelectrode; and
means for determining the photoresponse by maintaining a fixed potential and light intensity and measuring the DC component of the photoresponse.

Abstract
Devices and methods are provided for making a plurality of determinations of the local (site-specific) redox state of a liquid system, by employing a photoresponsive element, which can be independently irradiated at different sites to provide independently detectable signals.
