Title
(EN) PARTICLE MANIPULATION
(FR) MANIPULATION DE PARTICULES
Abstract
(EN)
The present invention relates to the manipulation and, more particularly, to the sorting of particles. Still more particularly, the present invention relates to the use of acoustic waves, including surface acoustic waves, for the manipulation and sorting of particles. In an example, the present invention may be used for the sorting of cells. In an aspect of the invention, there is provided a device for manipulating a particle in a fluid suspension, the device comprising: (a) a substrate having a surface; (b) an acoustic source configured to generate and deliver an acoustic wave within a region of the substrate surface; and (c) a pillar disposed on the surface of the substrate and the pillar is configured to receive a channel, the channel configured to receive the fluid suspension, wherein the acoustic wave delivered within the region of the substrate surface is delivered to the fluid suspension in the channel through the pillar. A method using the device of the invention is also disclosed.

La présente invention concerne la manipulation et, plus particulièrement, le tri de particules. Encore plus particulièrement, la présente invention concerne l'utilisation d'ondes acoustiques, y compris des ondes acoustiques de surface, pour la manipulation et le tri de particules. Dans un exemple, la présente invention peut être utilisée pour le tri de cellules. Dans un aspect de l'invention, l'invention concerne un dispositif pour manipuler une particule dans une suspension de fluide, le dispositif comprenant : (a) un substrat ayant une surface; (b) une source acoustique configurée pour générer et délivrer une onde acoustique à l'intérieur d'une région de la surface de substrat; et (c) un pilier disposé sur la surface du substrat et le pilier étant configuré pour recevoir un canal, le canal étant configuré pour recevoir la suspension de fluide, l'onde acoustique délivrée à l'intérieur de la région de la surface de substrat étant délivrée à la suspension de fluide dans le canal par l'intermédiaire du pilier. L'invention concerne également un procédé utilisant le dispositif de l'invention.
