    摘要: Microfluidic devices and methods that use cells such as cancer cells, stem cells, blood cells for preprocessing, sorting for various biodiagnostics or therapeutical applications are described. Microfluidics electrical sensing such as measurement of field potential or current and phenomena such as immiscible fluidics, inertial fluidics are used as the basis for cell and molecular processing (e.g., characterizing, sorting, isolation, processing, amplification.) of different particles, chemical compositions or biospecies (e.g., different cells, cells containing different substances, different particles, different biochemical compositions, proteins, enzymes etc.). Specifically, the present invention discloses a number of sorting schemes for stem cells, whole blood and circulating tumor cells, and extracting serum from whole blood.

    摘要: A measurement apparatus includes a generation section and a measurement section and performs a predetermined measurement using a flow channel device including a narrow channel through which particles pass by a flow of a fluid and a measurement electrode section provided in the vicinity of the narrow channel. The generation section generates, in the measurement electrode section, an AC voltage that is higher than a characteristic frequency defined by a conductance of the fluid including the particles in the narrow channel and an electrical double layer capacitance formed by the measurement electrode section and has a frequency range indicating a conductance corresponding to a size of the particles. The measurement section measures, while the AC voltage is applied to the measurement electrode section, an electrical amount including at least the conductance obtained when the particles pass through the narrow channel.

    摘要: The present disclosure provides an apparatus for sample introduction including a flow channel, a sample inlet, a metering unit, a separating unit, cell dischargers and, and a pressure controlling unit. The sample inlet is given a sample fluid such as blood. The sample inlet has a constricting hole that communicates with the flow channel for passage of a carrier fluid. The constricting hole has a diameter large enough for passage of a single cell contained in the sample fluid. The sample fluid is introduced into the flow channel through the constricting hole, and the cells in the sample fluid pass one by one through the constricting hole. The constricting hole does not exist inside the flow channel for passage of the carrier fluid, so that the diameter of the constricting hole does not affect the flow rate of the carrier fluid passing through the flow channel.
