Subject evaluation method

摘要

In an analyte evaluation method for evaluating an analyte, AC voltage is applied between a substrate electrode (2) on a substrate (4) and a counter electrode (8), and signals obtained from a marker (3) provided on an analyte bound to the substrate electrode are observed, wherein the frequency of the AC voltage is changed and the behavior of the average value of the marker signals is observed. A novel, highly-selective, low-noise method of evaluating a object of evaluation is thus achieved.
