N2 - A nonenzymatic glucose photobiosensor was developed based on Au-nanoparticle-decorated TiO 2 nanorods (NRs) under visible illumination. Au nanoparticles (NPs) absorbed the visible illumination, resulting in surface plasmon resonance (SPR). The SPR of the Au NPs indicated that there was a strong electric field around them, which promoted the transport of more electrons to the TiO 2 NRs and enhanced the glucose sensing properties. The sensing current under visible illumination was five times higher than in the dark when in 0.1 M NaOH solution at a potential of 0.17 V. Moreover, the Michaelis-Menten constant (K m ) of the Au NPs/TiO 2 NRs/FTO under visible illumination was 0.52 mM, which is much smaller than that reported previously. Moreover, these results indicate that the Au NPs/TiO 2 NRs/FTO under visible illumination feature outstanding properties as a nonenzymatic glucose photobiosensor.
