A novel self-cleaning, non-enzymatic glucose sensor working under a very low applied potential based on a Pt nanoparticle-decorated TiO2 nanotube array electrode

- The highly ordered TiO2 nanotubes array (the support material) with large specific surface area was prepared by anodization simply and easily.
- Pt nanoparticles (the catalyst) of 5 nm exhibit outstanding catalytic activity to glucose and anti-fouling property.
- The working potential of the prepared electrode is very low which shows good anti-interference ability and striking stability.
- The TiO2 material shows good chemical stability and self-cleaning ability.
