Abstract :
The design and development of a field deployable biosensor unit based on InAs quantum dots and a InGaAs quantum well hybrid structure is reported. The detection sensitivity of the sensor unit and in particular the weak light detection ability have been tested and analysed in detail. With a custom-made circuit for signal readout and a data processing unit equipped with an LCD screen for data display, the sensor unit 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 this sensor unit makes it a promising choice for the identification of bio-samples.
