Title:
誘電体微粒子濃縮装置
Document Type and Number:
Japanese Patent JP4548742
Kind Code:
B2
Abstract:
Microorganisms (dielectric microparticles) in a liquid sample are captured using a dielectrophoretic force. After quantifying and analyzing, the microorganisms thus captured are concentrated and collected. In an apparatus for concentrating dielectric microparticles, a liquid sample, which contains the microorganisms to be examined, is supplied from a liquid sample-holding unit holding the liquid sample and passes through a voltage-applied cell. During the passage, the microorganisms are captured on dielectrophoretic electrodes by a dielectrophoretic force. Then, the captured microorganisms are released from the dielectrophoretic force by ceasing the voltage application. At the same time, a release liquid supplied from a release liquid-holding unit is flown through the dielectrophoretic electrodes so that the concentrated microorganisms are released and collected into a collection unit as the target bacteria.
