An apparatus and method for sorting particles (237) in a laminar flow microfluidic channel includes a cantilevered coaxial flow injector (35) in a microfluidic device (100), the cantilevered coaxial flow injector (35) including an elongated cantilever element (35) integrated into the microfluidic device (100). A coaxial channel (200) runs through the elongated cantilever element (35), where coaxial channel (200) is sized to pass particles (237) of a predetermined size. An actuator (34) is coupled to the elongated cantilever element (35), for actuating said elongated cantilever element (35).
L'invention porte sur un appareil et un procédé qui permettent de trier des particules (237) dans un canal microfluidique à flux laminaire. L'appareil précité comprend un injecteur de flux coaxial en porte-à-faux (35) dans un dispositif microfluidique (100), l'injecteur de flux coaxial en porte-à-faux (35) comprenant lui-même un élément en porte-à-faux allongé (35) intégré dans le dispositif microfluidique (100). A travers l'élément en porte-à-faux allongé (35) s'étend un canal coaxial (200) d'une taille qui lui permet de laisser passer des particules (237) d'une dimension prédéterminée. Un actionneur (34) couplé à l'élément en porte-à-faux allongé (35) permet d'actionner ce dernier.
