Systems and methods are provided for detecting the presence of an analyte in a sample. A solid state electrochemical sensor can include a redox active moiety having an oxidation and/or reduction potential that is sensitive to the presence of an analyte immobilized over a surface of a working electrode. A redox active moiety having an oxidation and/or reduction potential that is insensitive to the presence of the analyte can be used for reference. Voltammetric measurements made using such systems can accurately determine the presence and/or concentration of the analyte in the sample. The solid state electrochemical sensor can be robust and not require calibration or re-calibration.
提供了用于检测样品中分析物存在的系统和方法。固态电
化学传感器可以包括一个氧化还原活性基团,其氧化和/或还原电位对固定在工作电极表面的分析物的存在敏感。可以使用一个对分析物存在不敏感的氧化还原活性基团作为参考。使用这种系统进行伏安测量可以准确地确定样品中分析物的存在和/或浓度。固态电
化学传感器可以坚固耐用,不需要校准或重新校准。
