Development of an electrochemiluminescence-based lab-on-chip using thin/thick film technologies

This work reports on design and fabrication of a compact lab-on-chip system, based on detection of electrochemiluminescence (ECL) through thin film sensors. The proposed system couples an optoelectronic platform to a disposable microfluidic chip. The optoelectronic platform includes amorphous silicon photosensors for detection of ECL, while the microfluidic chip contains the ECL electrodes and the biological solutions to be analyzed. Optoelectronic characterization of photosensors and preliminary test on the ECL electrodes by cycling voltammetry show the suitability of these devices for the achievement of low-noise and high sensitive system.
