Title:

ION-CONCENTRATION-POLARIZATION-TYPE BACTERIA DETECTION DEVICE, AND BACTERIA DETECTION METHOD USING SAME

Document Type and Number:

WIPO Patent Application WO/2022/211319

Kind Code:

A1

Abstract:

The present invention provides an ion concentration polarization (ICP)-type bacteria detection device, and a bacteria detection method using same, the device comprising: a channel unit including a first channel having an inlet part through which a fluid is injected, and a second channel having an outlet part connected to the first channel to discharge the fluid therethrough; an ion-permeable membrane layer disposed on the channel unit to provide an ion transfer path; and an electrode unit including a first electrode to which a negative voltage is applied, wherein ICP occurs in an area adjacent to a branch point between the channel unit and the ion-permeable membrane layer, and thus bacteria is concentrated from the fluid passing through the channel unit, and the first electrode is disposed closely to one side of the ion-permeable membrane layer and is provided so that water in the fluid is electrolyzed in an adjacent part of the first electrode to generate alkaline water.
