Chlamydia trachomatis is detected by electrochemical impedance spectroscopy using a mouse monoclonal IgG2a anti-MOMP antibody immobilized onto a Si electrode. Two types of electrochemical cells are used in this study, one with the electrode at the bottom and the other will the electrode on the side. Control experiments with Escherichia coli demonstrate this biosensor is not selective to Chlamydia trachomatis. Another control experiment with Chlamydia trachomatis immobilized onto mouse monoclonal IgG2a isotype antibody coated electrode obtains an increased charge transfer resistance (Rct) which is inversely proportional to the rate of electron transfer. These results demonstrate further investigations are needed to develop the Chlamydia trachomatis impedance biosensor.
