Surface Plasmon-Enhanced Photoelectrochemical Sensor Based on Au Modified TiO(2) Nanotubes

Based on the enhanced charge separation efficiency of the one-dimensional structure and strong surface plasmon resonance (SPR) of gold, a gold modified TiO(2) nanotube (Au/TiO(2)NTs) glucose photoelectrochemical (PEC) sensor was prepared. It could be activated by visible red light (625 nm). Under op...

description Based on the enhanced charge separation efficiency of the one-dimensional structure and strong surface plasmon resonance (SPR) of gold, a gold modified TiO(2) nanotube (Au/TiO(2)NTs) glucose photoelectrochemical (PEC) sensor was prepared. It could be activated by visible red light (625 nm). Under optimal conditions, the Au/TiO(2)NTs sensor exhibited a good sensitivity of 170.37 μA·mM(−1)·cm(−2) in the range of 1–90 μM (R(2) = 0.9993), and a detection limit of 1.3 μM (S/N = 3). Due to its high selectivity, good anti-interference ability, and long-term stability, the fabricated Au/TiO(2)NTs sensor provides practical detection of glucose. It is expected to be used in the construction of non-invasive PEC biosensors.
