Title
(EN) BATCH PARTICLE SORTING
(FR) TRI PAR LOTS DE PARTICULES
Abstract
(EN)
A system and a method for the batch sorting of particles are provided. An example of a batch sorting system includes a microfluidic ejector, a flow channel fluidically coupled to the microfluidic ejector at one end, and a reservoir coupled to an opposite end of the flow channel from the microfluidic ejector. A counter is disposed in the flow channel upstream of the microfluidic ejector to count particles prior to ejection from the microfluidic ejector. An optical sensor is to image the flow channel. A controller is configured to locate a target particle in the flow channel based, at least in part, on the image and capture the target particle in a collection vessel based, at least in part, on a count from the counter.

L’invention concerne un système et un procédé de tri par lots de particules. Un exemple d'un système de tri par lots comporte un éjecteur microfluidique, un canal d'écoulement couplé fluidiquement à l'éjecteur microfluidique au niveau d'une extrémité, et un réservoir couplé à une extrémité opposée du canal d'écoulement à partir de l'éjecteur microfluidique. Un compteur est disposé dans le canal d'écoulement en amont de l'éjecteur microfluidique pour compter les particules avant l'éjection de l'éjecteur microfluidique. Un capteur optique est destiné à imager le canal d'écoulement. Un dispositif de commande est configuré pour localiser une particule cible dans le canal d'écoulement sur la base, au moins en partie, de l'image et pour capturer la particule cible dans un récipient de collecte sur la base, au moins en partie, d'un comptage provenant du compteur.
