摘要

Pt nanoflower with excellent catalytic activity towards H_2O_2 was deposited on the surface of a screen-printed carbon electrode using potentiostatic technique to fabricate a disposable sensor for point-of-care glucose testing. Glucose oxidase was embedded via Nafion film. Field Emission Scanning Electron Microscopy was used to characterize the microstructure and morphology of the enzymatic electrodes. The results demonstrated that the size-controllable Pt NFs with dendrite structure were uniformly dispersed on the electrode surface, which can efficiently promote the electron transfer between glucose oxidase and electrode interface. The as-prepared electrode exhibited excellent analytical performances for the determination of glucose with a wide linear range of 0.5-20 mM and a high sensitivity of 67.57 μA mM~(-1) cm~(-2). Good accuracy of the proposed electrochemical method achieved in the determination of glucose in real samples.
