Abstract
A micro ion selective electrode (μISE) array to realize multiplex detection of heavy metal ions on one chip is reported in this paper. The micrometer scale device array derived from microfabrication processes demonstrated enhanced sensitivity, uniformity, and reduced response time compared to conventional ISE devices. Its detection limit for Pb2+, Cd2+, AsO2-, and Hg2+ can reach ppb level, within the permissible limits of drinking water. Our device demonstrates superb selectivity, and it is capable of detecting heavy metal ions in a wide range of temperature and pH value after calibration.
