DPV studies of the streptavidin/SPCE in Zobell’s solution at a modulation amplitude of 25 mV and a modulation time of 50 ms at room temperature after exposing with (a) streptavidin, EDC-NHS, probe, noncorresponding, and miR393a, and (b) hybridization with the complementary miR393a target (100 nM, 10 nM, 1 nM, 100 pM, 10 pM, 1 pM, and 100 fM). (c) DPV response curves of the probe-EDC-NHS-streptavidin-SPCE toward the miR393a concentration range of 10 μM–100 fM.
