Abstract
A biochemical sensor apparatus having an optical radiation source, a sensor array, and a photodetector array is disclosed. Each sensor of the sensor array includes fluorophores for fluorescence (generating response radiation) when mixed with analytes of interest and exposed to stimulus radiation. An array of photodetectors, such as a CMOS imaging array is used to detect the response radiation. The detected response radiation is converted to digital values and the digital values used to analyze various properties of the analytes present in the sensors.
