Abstract: In this paper, a sensing mechanism based on Microfluidics, for detection of dangerous heavy metals in liquids has been prepared. A pair of interdigitated electrodes (IDE’s) was fabricated on a glass substrate using a silver ink constituting nano-particle size molecules. The impedance between the pair of IDEs was measured for different samples with varied cadmium concentrations. The capability of these IDE’s for detecting very low to low concentrations (Picomolar to Millimolar) of Cadmium was explored. The response curve based on Impedance Spectroscopy Analysis of the IDE’s with the help of a Digital impedance testing equipment was plotted for detection of Picomolar, Nanomolar, Micromolar and Millimolar concentration levels of Cadmium sulfide compound in water. The averaged out results obtained showed coherently decreasing impedance values with increasing Cadmium sulfide concentrations in water
