Abstract:
1. A chip for cell sorting comprising: a substrate; and, provided on the substrate, the following: a first flow path which allows a sample fluid containing cells to flow down; second and third flow paths which are provided on both respective sides of said first flow path and which allow a buffer fluid not containing cells to flow down; a first reservoir for supplying the sample fluid containing the cells to the first flow path; a second reservoir for supplying the buffer fluid to the second and the third flow paths; a fourth flow path which allows a fluid to flow down, said fluid being formed by confluence of the sample fluid from the first flow path and the buffer fluid from the second and third paths; a cell detecting region provided on the fourth flow path for detecting cells flowing with the fluid flowing down the fourth flow path; a cell sorting region provided downstream of the cell detecting region of the fourth flow path for sorting the cells according to the type of the cells detected; at least two flow paths downstream of said cell sorting region, said flow paths allowing sorted cells to flow down, and wherein the first reservoir is formed with a boundary wall for holding the sample fluid containing the cells, said boundary wall being formed inside of the second reservoir.
