MICROFLUIDIC DEVICE FOR ELECTROCHEMICALLY REGULATING THE PH OF A FLUID THEREIN USING SEMICONDUCTOR DOPED WITH IMPURITY AND METHOD FOR REGULATING THE PH OF A FLUID IN A MICROFLUIDIC DEVICE USING THE SAME

摘要

The present invention is a) a cathode substrate; b) an anode substrate which is located opposite to the cathode substrate to form a reaction chamber with said cathode substrate; And c) electrochemical the pH of the fluid in that in comprises a non-conductor to separate the boundary of the cathode substrate and the anode substrate, at least one of the cathode substrate and the anode substrate are doped with the impurity semiconductor and the other is a metal electrode characterized using the microfluidic device and provides him a way to adjust the pH to adjusted. The microfluidic device of the present invention does not require a separate electrode, thereby does not require an electrical connection between the electrode and the external size of the microfluidic device, resolution, and manufacturing cost of the leak of simplicity, the chamber of the manufacturing process a it can be reduced. In addition, microfluidic devices of the present invention may incorporate a variety of biological analysis processes including a fine structure capable of adsorbing the biomolecule substance in the chamber of the cathode substrate, and can be easily manufactured by using a semiconductor manufacturing process . According to the method of the present invention, to adjust the pH of the fluid in the microfluidic device quickly and easily, and / or can be efficiently concentrated by the biomolecule substances. ; Electrolysis, pH, microfluidic devices, lab-on-a-chip, doped silicon, microstructure, cytolytic
