Potential measurement system for microfluidic channel

Abstract

Embodiments of the present invention relate to a potential measurement system for a microfluidic channel. The potential measurement system for a microfluidic channel according to the embodiments of the present invention may comprise: a microchannel into which a sample solution containing a sample is injected; a probe channel including a reservoir into which a buffer solution is injected, and an ion exchange membrane which extends from at least a portion of the reservoir and has an end connected to the microchannel; a measurement electrode which is electrically connected to the reservoir; and a measurement unit which applies a feedback voltage to the reservoir through the measurement electrode and measures a potential at a target location within the microchannel on the basis of the applied feedback voltage.

Dependencies are inferred from the claim text.
