Title
(EN) MICROCHIP WITH EXPANSION CHANNEL AND FLOWCYTOMETER USING THIS MICROCHIP
(FR) MICROCIRCUIT INTEGRE PRESENTANT UN CANAL AGRANDI ET CYTOMETRE DE FLUX UTILISANT LE MICROCIRCUIT INTEGRE
Abstract
(EN)
Disclosed is a microchip for a flowcytometer. A channel is expanded around a point, on which laser beams emitted from an optical unit are focused, so that focused sample particles slow down when they pass the expanded portion. This improves the detection intensity of sample particles.
(FR)
L'invention concerne un microcircuit intégré pour cytomètre de flux. Un canal est agrandi autour d'un point sur lequel des faisceaux laser émis d'un dispositif optique sont focalisés, de sorte que des particules échantillons focalisées ralentissent lorsqu'elles traversent la partie agrandie, ce qui améliore l'intensité de détection des particules échantillons.
