A device (103, 106, 112, 113, 110, 152, 158, 168, 170A, 170B, 170C, 182, 184, 250, 295) acts as a particle switch to transport and/or re-direct microparticles which are in a fluid suspension. The switch (103, 107, 112, 113, 110, 152, 158, 168, 170A, 170B, 170C, 182, 184, 250, 295) comprises at least three structural branches (e.g., 103a/103b/103c, 107a/107b/107c/107d, 110a/110b/110c, 110d/110e/110f, 110g/110h/110i, 152a/152b/152c, etc.); and the branches may be connected at a common junction (103, 107, 150, 158, 258). Particles (160, 164) can be transported along the branches as a result of the forces generated along that branch. Particles are transported into or out of the particle switch via the ends (e.g., 105a, 105b, 105c, 108a, 108b, 108c) of the branches. Particles can be switched from one branch into one of the other branches. Depending on the properties of the particles, the transportation mechanism may be traveling-wave-dielectrophoresis or traveling-wave- electrophoresis.
L'invention concerne un dispositif (103, 106, 112, 113, 110, 152, 158, 168, 170A, 170B, 170C, 182, 184, 250, 295) qui agit comme un commutateur de particules pour transporter et/ou réorienter les microparticules contenues dans une suspension fluide. Le commutateur (103, 107, 112, 113, 110, 152, 158, 168, 170A, 170B, 170C, 182, 184, 250, 295) comprend au moins trois branches structurales (par exemple, 103a/103b/103c, 107a/107b/107c/107d, 110a/110b/110c, 110d/110e/110f, 110g/110h/110i, 152a/152b/152c, etc.) pouvant être reliées par une jonction commune (103, 107, 150, 158, 258). Les particules (160, 164) peuvent être transportées le long des branches sous l'effet des forces générées sur ces branches. Les particules sont transportées vers/loin du commutateur de particules via les extrémités (par exemple, 105a, 105b, 105c, 108a, 108b, 108c) des branches. Les particules peuvent passer d'une branche à l'autre. Selon les propriétés des particules, le mécanisme de transport peut être la diélectrophorèse à ondes progressives ou la électrophorèse à ondes progressives.
