Abstract: An analyte identifying and sorting apparatus for sorting a target analyte based on an identification result of analytes dispersed in a liquid. The apparatus includes an identification unit including an analyte storage section configured to store analytes dispersed in a liquid, a pressure control section configured to feed the liquid to a flow path provided to extend downward from the analyte storage section, a light irradiation section configured to irradiate light to the analytes, an optical information measurement section measuring optical information of the analytes, and a determination section determining whether the analyte is a target analyte or a non-target analyte based on the optical information. Also included is a sorting unit that includes a sorting nozzle connected to the identification unit and sorts a sorted solution containing the target analyte to the vessel, an effluent collection section having a suction nozzle to suck and collect an effluent involving an effluent discharged from a tip of the sorting nozzle, and a collection vessel configured to collect the sorted solution containing the target analyte. A moving unit moves the sorting nozzle and/or the collection vessel, a control unit moves the sorting nozzle and/or the collection vessel based on the optical information, and a stirring unit including a stirring member in an inner space of the analyte storage section.

Abstract: A screening apparatus includes a light permeable measurement chip having a well retaining a liquid including microparticles, a measuring section acquiring optical information of the microparticles obtained by illuminating the microparticles, an analyzing section that extracts optical information of the microparticles, a receiving plate receiving a microparticle selectively picked up from the measurement chip, a moving section moving the measurement chip and the receiving plate against the measuring section, and a collecting section for collecting a microparticle by sucking with the suction-ejection capillary and ejecting on the receiving plate. A distal-end outer dimension of the capillary is greater than a width of the well. The capillary sucks the target microparticle at a position where the distal end of the capillary and the measurement chip are spaced by a predetermined distance and a central axis of the distal end of the capillary and a central axis of the well are mutually displaced.
