Abstract

We have designed and developed a field deployable biosensor unit based on a novel proprietary quantum dots-quantum well hybrid structure. We analyzed in detail the detection sensitivity and in particular weak light detection and analysis of the semiconductor optoelectronic device. We designed a readout circuit and a data processing unit to handle the response signal. The sensor unit is equipped with a LCD element for data display and can be used in a centrally managed real-time monitoring system such as for infectious disease management and bio-aerosol monitoring. The high sensitivity of our sensor enables fast and reliable spectral results to aid rapid identification of biological samples.
