Abstract
An electrowetting-on-dielectric (EWOD) microfluidic device comprises at least one integrated electrochemical sensor, the electrochemical sensor comprising: a reference electrode; a sensing electrode; and an analyte-selective layer positioned over the sensing electrode. In some embodiments, the electrochemical sensor measures a concentration of an analyte in a fluid sample exposed to the electrochemical sensor based on a potential difference between the reference electrode and the sensing electrode. The first analyte and the second analyte can be selected from a group consisting of K, Na, Ca, Cl, HCO, Mg, H, Ba, Pb, Cu, I, NH4, (SO4).
