摘要
A lab-on-a-chip (LOC) device for detecting target nucleic acid sequences in a fluid, the LOC device having electrochemiluminescent (ECL) probes for detecting the target nucleic acid sequences, each of the probes having an ECL luminophore for emitting photons when in an excited state, a functional moiety for quenching photon emission from the ECL luminophore by resonant energy transfer, electrodes for receiving an electrical pulse to excite the ECL luminophores, detection photodiodes for exposure to the photons emitted by the ECL luminophores, and, at least one calibration photodiode for exposure to ambient light, wherein during use, a difference between the output from any of the detection photodiode and the output from the calibration photodiode is compared to a predetermined threshold difference such that output differences greater than the predetermined threshold indicate the target is present.
