DIAGNOSTIC TEST MODULE WITH A LOC WITH INTEGRAL PHOTOSENSOR AND EXCITATION LED FOR DETECTION OF HYBRIDIZATION ASSAY RESULTS

摘要

A test module for detecting hybridization of probes with target nucleic acid sequences, the test module having a receptacle for receiving a biological sample with target nucleic acid sequences, an array of probes for hybridization with the target nucleic acid sequences, an excitation light emitting diode (LED) for illuminating the array of probes, CMOS circuitry having a photosensor for sensing a fluorescence emission from any of the probes in the array that have hybridized with the target nucleic acid sequences such that the CMOS circuitry is configured to use outputs from the photosensor to generate a signal indicative of the probes that have hybridized, wherein, the array of probes and the CMOS circuitry are integrated on a lab-on-a-chip (LOC) device contained within the test module.
