A sensor for the detection of an analyte in a biological sample includes a substrate, a working electrode and counter electrode formed on a surface of the substrate, and a receptor functionalized or chemically functionalized to a surface of an exposed portion of the working electrode. The receptor can selectively bind to the analyte of interest and the analyte once bound is detectable by measuring the current flow between the working electrode and counter electrode.

生物样本中分析物的传感器包括基底、形成于基底表面的工作电极和对电极,以及功能化或
化学功能化于工作电极暴露部分表面的受体。受体可选择性地与感兴趣的分析物结合,一旦与分析物结合,就可通过测量工作电极和对电极之间的电流进行检测。
