A Micro-Fabricated Non-enzymatic Urine Glucose Sensor Using Nafion Coated Nanoporous Pt Composite Electrodes
A micro-fabricated non-enzymatic urine glucose sensor was newly developed and characterized by using Nafion coated nanoporous Pt composite electrodes for u-health care applications. In order to detect urine glucose effectively, thin layer of Nafion film was coated on all the surface of nanoporous Pt electrode for anti-protein-fouling. The fabricated sensor exhibited extremely high sensitivity of 0.728 μA/mMcm 2 , a detection limit of 10 μM, and wide detection range up to 21.68 mM. It also showed extremely stable and fast response to the urine glucose without any adsorption on the surface of sensor.
