摘要: Abstract A glucose biosensor was developed, which based on Prussian blue-gold (PB-Au) nanocomposite films and platinum nanoclusters (Pt-NCs). blue (PB), as an electron mediator, electrochemically deposited the glass carbon electrode (GCE) in presence of chloroauric acid, forming PB-Au films. Then, Pt-NCs were electrodeposited to construct a bilayer film. At last, oxidase modified with film Nafion (Nf) used prevent (GOD) from leaking off. The resulting amperometric exhibited fast response time (within 8 s) linear calibration range 3.0 μM 1.1 mM low detection limit 1.0 μM (S/N = 3). With operating potential, showed little interference possible interferents, including acetum uric acid arginine, indicating excellent selectivity. improved performances for electrocatalysis-oxidation ascribed high surface-to-volume ratio catalytic activity nanoparticles. combination would open new horizons fabrication biosensors biocatalysts.
