摘要：

This paper presents a non-enzymatic magnesium oxide (MgO) thin film potential sensor with sensing capabilities for ascorbic acid (AA) solutions in the typical concentration range of 0.007 mM to 2 mM in the human body. When measured with AA solutions of different concentrations, the average sensitivity reaches 20.73 mV/decade. At the same time, the linearity achieved in the measurement of five concentration intervals from low to high also reached 0.97. Experimental results demonstrate the sensing potential of the proposed MgO thin film sensor in measuring AA. In addition, reproducibility experiments confirmed that the MgO thin film sensor preparation method proposed in this study has good stability.
