  • Publication number: 20160263575
    Abstract: A particle manipulation system uses a MEMS-based, microfabricated particle manipulation device which has an inlet channel, output channels, and a movable member formed on a substrate. The movable member moves parallel to the fabrication plane, as does fluid flowing in the inlet channel. The movable member separates a target particle from the rest of the particles, diverting it into an output channel. However, at least one output channel is not parallel to the fabrication plane. The device may be used to separate a target particle from non-target material in a sample stream. The target particle may be, for example, a stem cell, zygote, a cancer cell, a T-cell, a component of blood, bacteria or DNA sample, for example. The particle manipulation system may also include a microfluidic structure which focuses the target particles in a particular portion of the inlet channel.
