Abstract
An optical sensor effective for (i) exciting an analyte-sensitive fluorophore, exposed to an unknown concentration of the analyte for which the fluorophore is sensitive, with radiant energy from an excitation source, (ii) measuring the extent to which luminescence of the excited fluorophore is quenched by presence of the analyte, (iii) ascertaining the concentration of analyte to which the fluorophore is exposed from such measurement, and (iv) reporting the ascertained concentration. The sensor is preferably an epi-fluroescence confocal optical detector, and preferably performs step (ii) by employing a summing amplifier.
