1. A fluid analyte sensor, comprising:

  • an array of photoelectrocatalytic elements, a respective one of which is configured to be exposed to the fluid, if present, and to respond to photoelectrocatalysis of at least one analyte in the fluid that occurs in response to impingement of optical radiation upon the respective photoelectrocatalytic element;

    an array of semiconductor light emitting sources, a respective one of which is configured to impinge the optical radiation upon the respective one of the photoelectrocatalytic elements; and

    an array of heaters that is separate from the array of semiconductor light emitting sources, a respective one of the heaters being configured and independently regulated to separately generate thermal energy and apply the thermal energy to only the respective photoelectrocatalytic element so as to affect interaction between the at least one analyte and the array of photoelectrocatalytic elements.
