A low-cost and enzyme-free glucose paper sensor is presented as a promising alternative to glucose test strips. This paper-based glucose sensor is prepared with molecularly imprinted (MIP) polyaniline (PANI) electrode. The determination of glucose concentrations was studied by the impedance change of the paper sensor before and after the blood samples dispensing at a low frequency. A comparison of the linear and polynomial regression was applied to analyze the impedance ratio as a function of glucose concentrations. The proposed glucose paper sensor showed a limit of detection (LoD) of 1.135 mM. This novel and non-enzymatic paper sensor suggests a low-cost glucose test assay and can improve the quality of routine testing for diabetic patients.
一种低成本且无酶的葡萄糖纸传感器被提出，作为葡萄糖测试条的一种有前景的替代方案。这种基于纸的葡萄糖传感器是用分子印迹（MIP）聚苯胺（PANI）电极制备的。通过在低频下在血样 dispensing 前后纸传感器的阻抗变化来研究葡萄糖浓度的测定。应用线性和多项式回归比较来分析作为葡萄糖浓度函数的阻抗比。所提出的葡萄糖纸传感器的检测限（LoD）为1.135 mM。这种新型非酶纸传感器表明了一种低成本的葡萄糖测试方法，并且可以提高糖尿病患者常规检测的质量。
原文中“dispensing”可能有误，结合语境猜测可能是“接触”之类的意思，但按照要求未做修改。
