ABSTRACT

In this paper, glucose quantitative detection by biological sensor and electrochemical capacitance data treatment was studied. The taste cells were fixed on carbon screen-printed electrode. Electrochemical capacitance responses of cell-based sensor to sucrose in different concentrations and related mixtures were measured. Glucose quantitative analysis results demonstrated that the proposed method had quantitative determination abilities toward glucose and related mixtures. The signal-to-noise ratio index presented qualitative discrimination abilities to different glucose mixtures. Negative control results indicated that the receptor-free cells showed no perception ability for glucose. The proposed method is promising in sugar rapid detection.

摘要

本文研究了生物传感器和电化学电容数据处理的葡萄糖定量检测。味觉细胞固定在碳丝网印刷电极上。测量了基于细胞的传感器对不同浓度蔗糖和相关混合物的电化学电容响应。葡萄糖定量分析结果表明，该方法对葡萄糖及相关混合物具有定量测定能力。信噪比指数表现出对不同葡萄糖混合物的定性区分能力。阴性对照结果表明无受体细胞对葡萄糖没有感知能力。所提出的方法在糖的快速检测中很有前景。
