Title
(EN) PARTICLE SORTING USING MICROFLUIDIC EJECTORS
(FR) TRI DE PARTICULES À L'AIDE D'ÉJECTEURS MICROFLUIDIQUES
Abstract
(EN)
A system and a method for sorting particles are provided. An example of a particle sorting system includes an array that includes a number of microfluidic ejectors. An optical sensor is focused on the array. A controller is used to identify a target particle proximate to a microfluidic ejector, and activate the microfluidic ejector to eject the target particle into a collection vessel.

L'invention concerne un système et un procédé de tri de particules. Un exemple d'un système de tri de particules comprend un réseau qui comprend un certain nombre d'éjecteurs microfluidiques. Un capteur optique est focalisé sur le réseau. Un dispositif de commande est utilisé pour identifier une particule cible à proximité d'un éjecteur microfluidique, et activer l'éjecteur microfluidique pour éjecter la particule cible dans un bac collecteur.
