Abstract
Provided is a microfluidic device for electrochemically regulating the pH of a fluid comprising: a cathode substrate; an anode substrate facing the cathode substrate and forming a reaction chamber with the cathode substrate; and a nonconductor which forms a boundary between the portions of the cathode substrate and the anode substrate that are capable of contacting one another, wherein at least one of the cathode substrate and the anode substrate is a semiconductor doped with impurities and the other is a metal electrode.
