Abstract
A microparticle trapping device includes: a fluid channel configured to be injected with a fluid including a microparticle; first and second electrodes configured to generate an electric field in the fluid channel; and an electrical insulator formed with at least one opening between the first and second electrodes in the fluid channel. The electrical insulator is disposed between the first and second electrodes so that an inhomogeneous electric field is made through the at least one opening between the first and second electrodes in the fluid channel, and the still other aspect is configured to trap the microparticle through dielectrophoresis.
