Microfluidic graphenised-paper electroanalytical devices (µGPED) for adsorptive cathodic stripping voltammetric detection of metal contaminants. PhD. University of the Western Capehttps://hdl.handle.net/10566/14689Philosophiae Doctor - PhDThe need for clean, non-toxic drinking water supplies, free of pollutants and metal contamination is vital in impoverished areas and the developing world alike. With this in mind, the development of accurate, inexpensive, portable and simple devices for remote sensing applications is therefore pivotal for early detection and the prevention of illnesses. Over the last two decades, adsorptive stripping voltammetry (AdSV) has emerged as a superior detection method over common analytical techniques due to its low-cost instrumentation, unskilled labour and ability to detect a wide range of analytes.enTrace metal analysisPaper-based microfluidicsSquare-wave adsorptive stripping voltammetryGrapheneElectrochemical reductionNanocompositeGold nanoparticlesChemical sensorInkjet printingWax patterningUniversity of the Western Cape
