A Microfluidic System with Nonenzymatic Glucose Sensor

摘要

In this paper, we report an amperometric-type enzymeless glucose sensor system based on nanoporous platinum (Pt) and platinum/platinum oxide (Pt/PtO) reference electrode, which are integrated with microfluidic chip. This microchip system is comprised of microfluidic transport channels and a nonenzymatic glucose sensor system with nanoporous Pt electrode. From this microfluidic chip system, rinsing and reconditioning of sensor can be possible and multiple-use sensor system can be achieved. The sensitivity of developed system was 0.28 μA/mM when tested with glucose solution diluted in PBS buffer.
