DEVICE FOR CONTROLLING PARTICLES

摘要

Provided is a particle control device for controlling fine particles. The particle control device includes: a base with a predetermined area and including an insulator; a first electrode and a second electrode disposed on the base such that they are separated from each other by a predetermined distance; and a fluid flow path disposed on the base so as to pass between the first electrode and the second electrode and to allow a solution to flow. The first electrode includes a plurality of branch electrodes with fine widths, each branch electrode having one end that is adjacent to the second electrode, with the fluid flow path interposed between the branch electrode and the second electrode.

1. A particle control device for controlling fine particles, the particle control device comprising:
a base with a predetermined area and including an insulator; a first electrode and a second electrode disposed on the base such that they are separated from each other by a predetermined distance; and a fluid flow path disposed on the base so as to pass between the first electrode and the second electrode and allow a solution to flow, wherein the first electrode includes a plurality of branch electrodes with fine widths, each branch electrode having one end that is adjacent to the second electrode, with the fluid flow path interposed between the branch electrode and the second electrode, and wherein the fine particles that are between the first electrode and the second electrode are controlled due to a dielectrophoretic force between the first electrode and the second electrode by applying powers having different polarities to the first electrode and the second electrode.
