METHOD OF OPTIMIZING MICROPARTICLE SUCTION CONDITION AND MICROPARTICLE SEPARATION DEVICE

摘要

In the present technology, the timing at which suction is performed is optimized in order to enhance the microparticle separation performance in a technology for separating target microparticles in a microchip. For this purpose, the present technology provides a method of optimizing a microparticle suction condition, and the like, using a microchip having a main flow channel through which a liquid containing a microparticle flows, a microparticle suction flow channel arranged coaxially with the main flow channel, and a branch flow channel branching from the main flow channel. The method includes: a branch point specifying process of specifying a branch point at which the branch flow channel branches from the main flow channel; and a time assignment process of assigning a time T₁ to be applied to suction of the microparticle, on the basis of a distance between a position of the microparticle and the branch point at a time point when a predetermined time T_X has elapsed from a time when the microparticle passed through a predetermined position on the main flow channel.
