Abstract
A particle screening device is provided. The particle screening device comprises: a substrate including a first side and a second side opposite to the first side; a micropore array formed on the substrate, wherein each micropore penetrates through the substrate from the first side to the second side and has a size configured to at least permit particles smaller than target particles flow through; and electrodes formed on at least one side of the first and second sides of the substrate and around at least some micropores, wherein the electrodes are configured to generate an electric field at corresponding micropores.

A particle screening device, comprising:
- a substrate including a first side and a second side opposite to the first side;
- a micropore array formed on the substrate, wherein each micropore penetrates through the substrate from the first side to the second side and has a size configured to at least permit particles smaller than target particles to flow into the micropore at the first side of the substrate, through the micropore, and flow out of the micropore at the second side of the substrate;
- and
- electrodes formed on at least one side of the first and second sides of the substrate and around at least some micropores, wherein the electrodes are configured to generate an electric field at corresponding micropores so as to achieve DEP of the target particles in the electric field, such that the target particles are attracted to and captured at the micropores while the particles smaller than the target particles flow out of the micropore at the second side of the substrate.
