We are developing a biosensor using luminol electrochemiluminescence and printed electrodes. Unlike fluorescence, electrochemiluminescence does not require a light source, has no background light, is highly sensitive, and has a wide calibration range. It has already been applied to the measurement of glucose, lactate, urea, sIgA, coronavirus-neutralizing antibodies, glycated albumin, and organophosphorus compounds. Recently, we have also been developing a wireless electrochemiluminescence biosensor using a smartphone camera and electromagnetic wireless power transmission. In this study, we investigated electropolymerization methods to immobilize luminol on a printed electrode. We also immobilized enzymes on the same electrode chip, focusing on on-site measurements for POCT.
