MICROCHIP AND METHOD OF CELL SORTING

摘要

[PROBLEMS] To provide a microchip for cell sampling whereby desired cells can be quickly and accurately sampled from a large number of cells with the combined use of the advantages of a system using optical tweezers and anoth er system using microchannels. [MEANS FOR SOLVING PROBLEMS] A microchip for cell sampling which is provided, on a single baseboard, with: a cell feeding channel for feeding a cell-containing liquid and flowing the same; and a ce ll sampling channel for sampling a portion of the cells passing through the cell feeding channel; wherein the cell feeding channel and the cell sampling channel have each a liquid feeder port connected to a liquid feeder mechani sm at one end and a liquid discharge port connected to a drainage mechanism at the other end and intersect with each other at the midway thereof.
