Abstract:
1. A method of isolating a particle of interest from a plurality of particles in a fluid sample which comprises: identifying the particle of interest in a fluid stream flowing through a primary microchannel; inducing a fluid displacer in a closed-loop fluid circuit to give a secondary flow which causes a flow path and direction of the particle of interest that are different from that of the plurality of particles, wherein the closed-loop fluid circuit is a conduit having a fluid therein, said conduit links, in a closed-loop, a first side of the fluid displacer to a first side of the primary microchannel and a second side of the fluid displacer to a second side of the primary microchannel, such that the fluid displacer, when induced, simultaneously causes the first side of the fluid displacer to push the fluid in the conduit toward the first side of the primary microchannel and the second side of the fluid displacer to pull the fluid in the conduit from the second side of the primary microchannel toward the second side of the fluid displacer.
