Abstract
Here we report an electrochemical ELISA approach for cardiac Troponin T (cTnT) determination based on a lateral flow membrane with underlying screen printed electrodes ( $<100~\Omega $ /cm2). The thick film transducer was modified with the anti-cardiac Troponin T antibody via physisorption and the electrochemical performance of the immunosensor was evaluated using cyclic voltammetry. The capture antibody coated immunoelectrode employed for electrochemical determination of Troponin T antigen used a sandwich assay format with horseradish peroxidase conjugated signaling antibodies held in the track of a lateral flow sensor strip. A simple two step procedure realized signal acquisition within <20 min (total assay time). The lateral flow electrochemical immunosensor response resulted in a calibration curve with linear response (0–700 ng/ml cTnT) with limit of detection of 0.15 ng/ml.
