Title:
微粒子分離装置及び方法
Document Type and Number:
Japanese Patent JP5700598
Kind Code:
B2
Abstract:
Micropillars are arranged a first row up to an nth row, the micropillars in one row are disposed at the same interval “a” from each other, and each of the rows is disposed in a position shifted by a distance “b” with respect to an immediately preceding upstream row, in a row direction. A liquid that contains particles flows through between the micropillars. A voltage is applied from a power supply to electrodes, thereby generating an electric field in a flow channel. The micropillars are electrical insulating structures, so in regions of narrow intervals between the micropillars, electrical lines of force are dense and strength of the electric field is high, and in regions of wide intervals between the micropillars, electrical lines of force are sparse and the strength of the electric field is low.
