Abstract
Section titled âAbstractâThis paper reports a flexible, diamond-polymer chemical sensor with three microelectrodes, which features a wide aqueous potential window and low background current from diamond and mechanical flexibility from the polymer.An improved wafer transfer process is developed to transfer boron-doped polycrystalline diamond (BDD) onto a thin Parylene-C substrate with good uniformity, strong adhesion, and high yield.The as-fabricated sensor shows a much wider potential window compared to an Au electrode, and a sensitivity of ~0.018mA/mm 2 ÎmM through cyclic voltammetry for Ru(NH 3 ) 6 2+/3+ and 0.0012”A/mm 2 ΔM through chronoamperometry for dopamine (DA).
