Design and fabrication of microfluidic device for mercury ions detection in water

The presence of heavy metal ions such as Lead (Pb²⁺), Mercury (Hg²+), Cadmium (Cd²+), Arsenic (As³+) and Chromium (Cr³) in water cause serious and long-term effects on human health. In particular, they may cause kidney damage, liver damage, lung cancer, neurotic disorder, anemia, discoloration of hands and feet. Hence detection and quantification of these metal ions are important for health care and prevention of serious diseases. This paper aims at the design, analysis and fabrication of microfluidic device for improved mixing performance using herringbone type of micromixer for sensing of mercury ions in water.
