Abstract

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.
