In this paper, we propose to design, simulate and fabricate a novel device design that would be capable of removing heavy metal ions like Lead or Arsenic from the Blood serum. The basic design of the device comprises of micro-needles at the inlet and the outlet, followed by a micro-channel where is blood is made to flow through a series of alternating constrictions. Every constriction has a coating of Carbon Aerogel to remove the Heavy metal ions like Pb. The design also eliminates the need for a valve or a micro pump as we ensure unidirectional flow by having fewer needles at the outlet as compared to the inlet and be placed in two regions of differential pressure. The present device (with surface dimensions of 100 × 150 × 75 microns) allows for blood filtration at the rate of 62.55 ml per week. Since the device has a slow filtration rate, multiple such Point-of Care device would be worn by the affected patients.
