Optimization of (a) wash buffer volume and binding times for (b) the target antigen (cTnI) and detection antibody, (c) the target antigen (cTnI)/detection antibody complex and the capture antibody, and (d) TMB enzyme–substrate with capture antibody/antigen/detection antibody complex for the proposed ELISA protocol in the developed microfluidic platform. The error bars represent ± standard deviation of n = 3 samples.
