Title:
CHANNEL CHIP, DIELECTROPHORETIC DEVICE, AND CONTROL VOLTAGE CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/024238
Kind Code:
A1
Abstract:
A channel chip (11) comprises a substrate (21), fluid wells (FW), a pair of first electrodes (33a), (33b), and a pair of second electrodes (43a), (43b). A sample fluid and a reference fluid can be injected into the fluid wells (FW). By applying a control voltage, the pair of first electrodes (33a), (33b) can cause a dielectrophoretic force to act on dielectric particles (P1) contained in the sample fluid which has been injected into the fluid wells (FW). The pair of second electrodes (43a), (43b) are arranged at locations different from those of the pair of first electrodes (33a), (33b). The control voltage applied between the pair of first electrodes (33a), (33b) is corrected on the basis of the impedance between the pair of second electrodes (43a), (43b) that has been measured by means of the reference fluid which has been injected into the fluid wells (FW).
