QUANTUM DOTS FOR WASTE WATER: A FUTURE PURIFIER

It is shown that detections of water pollutants is possible using quantum dots exploiting their ability to make link with specific pollutant in waste water and show signal through changed optical emissions. These are better than dye-based sensors due to longer life time of emissions and compatibility of being used in conjunction with other techniques like molecularly imprinted polymers (MIP). Imprinted fluorescence transduction platform can specially bind the trace target pollutant in complicated matrix and bring about the fluorescence quenching of the sensor to a degree that may be related to the amount of the target pollutant. This brief review presents recent trends in fabrication methodology and applications of quantum dots and MIPs.
