  • FINE PARTICLE DISPENSING DEVICE, FINE PARTICLE ANALYSIS DEVICE, REACTION DETECTION DEVICE, AND METHOD USING SAID DEVICES
    Publication number: 20190339189
    Abstract: The object of the present invention is to provide a technique for dispensing cells as single cells. The above problem can be solved by an apparatus for dispensing particles comprising a transparent hollow pipette for dispensing sample liquid containing particles, and an image capturing means, wherein the devise has means for capturing two or more images of the dispensing liquid in the hollow pipette; means for comparing two or more shot images, distinguishing a moved particle-like substance from an unmoved particle-like substance in the image-captured particle-like substances, and identifying the moved particle-like substance as a suspended particle; and means for dispensing a sample liquid containing a target number of suspended particles.
