ABSTRACT- The emerging analytical technique of coupling microfluidic devices with chemiluminescence detection provides a powerful tool for environmental monitoring. This is a solution for portable detection systems because microfluidic devices have the advantage of low reagent consumption, low waste production, cost effectiveness, small sample volume and enables high sample throughput. The incorporation of chemiluminescence as the detection method is ideal due to its simple instrumentation and measurement set up which provides highly sensitive results. Here, we have demonstrated the luminol chemiluminescence reaction within a micro reactor for the determination of hydrogen peroxide in rainwater in order to produce a portable low powered battery operated chemiluminescence detection system to measure concentrations of hydrogen peroxide at levels less than 10M. Immobilisation of the luminol reagents onto controlled pore glass (CPG) were also investigated and incorporated within the micro reactor to produce a reagentless system for hydrogen peroxide determination to improve the portability of the system. Chemiluminescence reactions can be incorporated with immunoassays improving selectivity and providing a range of applications for the detection of environmental toxins. Developments in this for environmental E-coli screening will also be presented.
