主权项

1. A device comprising
a single transparent fluorine-doped tin oxide coated substrate that has been etched to generate at least fifty etched regions, wherein each etched region comprises an addressable conductive lead, and wherein the surface of the substrate comprising the etched regions is hydrophobic or has been treated to be hydrophobic; a plurality of photoconductive mixed metal-oxides disposed on the conductive leads; a layer of insulating epoxy applied to the surface of the substrate not covered by the mixed metal-oxides; a chamber comprising an electrolyte buffer; a light source; and a measuring apparatus,wherein the measuring apparatus is electrically coupled to the conductive leads and is configured to measure a change in voltage or current, the chamber configured to receive the substrate and wherein the light source illuminates one or more of the regions of photoconductive mixed metal-oxides.
