PROBLEM TO BE SOLVED: To increase speed and accuracy of particle selection by improving a conventional particle operation system.SOLUTION: A particle operation system uses an MEMS-based microfabricated particle operation device having an inlet channel, an outlet channel, and a movable member formed on a substrate. The movable member moves in parallel with a fabrication plane like fluid flowing in the inlet channel. The movable member separates a target particle from a remaining particle to divert the target particle to the outlet channel. However, at least one outlet channel is not parallel with the fabrication plane. The device is used to separate the target particle from a non-target material in a sample flow. The target particle can be a stem cell, embryo, cancer cell, T cell, blood composition, bacteria, or DNA sample. The particle operation system includes a microfluidic structure that focuses a target particle on a specific area of the inlet channel. |
