Microfluidic Analysis for Organophosphate Pesticides

摘要

Composite electroless coating technique was employed to fabricate planar gold microelectrode modified with nano zirconia for organophosphate pesticide detection. Experimental conditions to obtain the best analytical signal were optimized including the doping level of nano particles in the sensing film. The nano zirconia showed a strong affinity toward the phosphate group on the parathion molecules, which provides Sensitivity and selectivity of the sensing film.
