Electrochemical impedance monitoring of immunochemicalreactions using varying IDE geometries for signal enhancement

摘要

Electrochemical Impedance Spectroscopy (EIS) has been applied to the detection of analytes for immunosensors [1-3]. The development of hand held devices based on this technique is a very promising prospect for point-of-care applications and is an attractive alternative to laboratory-based immunochemical analysis [1, 4]. The work in this paper will focus primarily on the development of an EIS method of transduction for immunoassay detection that could be potentially introduced into a hand held point-of-care device. Varying geometries of IDEs will be reported and discussed to improve the detection of antigen.
