文摘
- •
WO3 nanoparticles were synthesized by hydrothermal method.
- •
The modified WO3/ITO electrodes were electrochemically characterized.
- •
The nitrite biosensor was fabricated as proof of concept with ccNiR/WO3/ITO structure.
- •
The analytical performance of the WO3 based biosensors achieved a sensitivity up to 2143 mA M−1 cm−2 with a Michaelis–Menten constant between 37 and 47 μM.
