In this paper, the L-ascorbic acid (L-AA) biosensor based on magnetic beads-ascorbate oxidase/graphene oxide/indium gallium zinc oxide/aluminum (MBs-AOX/GO/IGZO/Al) membrane was integrated with the potentiometric measurement system with the microfluidic framework in order to investigate the different sensing characteristics under the static condition and the dynamic condition. The L-AA biosensor showed the average sensitivity of 78.9 mV/decade (25 °C) under the static condition, and it showed the average sensitivity of 81.7 mV/decade (25 °C) at the optimal flow rate (25 μl/min). Besides, the XBee module was used to apply in the remote detection for the L-AA biosensor, and the experimental results were shown the average sensitivity of 78.7 mV/decade (25 °C). Moreover, we also investigated various experiments, such as temperature effect, hysteresis effect, and lifetime. These experimental results would be beneficial to the development of the L-AA biosensor based on electrochemical detection. |
