In this study, with the aim of adapting an enzyme-linked immunosorbent assay (ELISA) system for point-of-care testing (POCT), we propose image analysis method ELISAs using a centrifugal microfluidic device that automatically executes assay. The developed can be used to quantify color development reaction on TMB (3,3',5,5'-tetramethylbenzidine) substrate. conventional ELISA, stopping reagents are required at end reaction. contrast, analyze in color-developing without reagent. This contributes reduction total time. devices study could execute reagent control by steady rotation. demonstration and analysis, calibration curve mouse IgG detection was successfully prepared, it confirmed had same performance as method. Moreover, changes amount over time equal endpoint obtained within 2 min from start As before approximately 7.5 min, ELISA detect just 10 min. methods plate reader, 90 manual handling microwell plates, case automatic devices, 30 were required. realized proposed is immunochromatographic lateral flow assay; therefore, expected performed sufficiently adapt POCT.
