Co-Cu alloy nanoparticles decorated TiO2 nanotube arrays for highly sensitive and selective nonenzymatic sensing of glucose

- Co-CuNP/TDNT nonenzymatic glucose sensor was fabricated.
- Two linear range of detection with high sensitivity of 4651.0 μA mM−1 cm−2 up to 5 mM and 2581.70 μA mM−1 cm−2 from 5 mM to 12 mM.
- Highly selective with low detection limit of 0.6 μM.
- Tested for estimation of serum glucose levels.
