Abstract (en)

[origin: US6465225B1] For manipulation of particles in a fluidic microsystem (15) in which the particles are moved in a predetermined reference direction in a suspension liquid, the microsystem (15) is closed off at least at its end (17a, 17b) pointing to the reference direction. The particles move under the influence of centrifugal forces and/or gravitational forces in the suspension liquid which is stationary in relation to the microsystem (15), with the centrifugal forces and/or gravitational forces essentially extending parallel to the reference direction. Furthermore, the particles in the microsystem (15) are exposed to deflection forces whose direction differs from that of the reference direction. (FIG. 1).
