摘要

•A screen-printed electrochemical sensor was integrated on EWOD-based lab-on-a-chips.•The chips could control an analyte concentration with T-junction EWOD electrodes.•The system could effectively analyze the concentrations of K4Fe(CN)6 and H2O2.•The results showed medium sensitivity, moderate detection limits and high stability.•The total analysis time including droplet mixing and CV measurement was shorter than 14 s.
