Abstract

We report the integration of artificial three-dimensional (3D) enzyme networks into SU-8 photoresist-converted porous carbon electrodes to realize highperformance amperometric nitrate sensors. The sensor provides an improved lifespan that allows for long-term monitoring of nitrate ions. The artificial enzyme is formed by introducing both graphene oxide (GO) and Vitamin B12 (Vit-B12) into the converted porous carbon. The enzymatic electrode serves as the working electrode of the sensor to detect nitrate ions in the sap solution of maize plants. It is demonstrates that the sensor has high sensitivity and selectivity to nitrate ions, as well as high stability over at least seven days with almost no performance degradation.
