Electrochemical sensor

摘要

Disclosed herein is an electrochemical sensor for detecting an analyte. The sensor comprises an electrode, a redox active species that is electrochemically accessible to the electrode, and a binding moiety capable of associating with the analyte, wherein association of the binding moiety with the analyte affects the electrochemistry of the redox active species. Also disclosed herein is a method for detecting the presence of an analyte in a sample.
