Title
(EN) MICROFLUIDIC PRODUCTION OF MONODISPERSED SUBMICRON EMULSION THROUGH FILTRATION AND SORTING OF SATELLITE DROPS
(FR) production microfluidique d'une Émulsion infÉrieure au micron monodispersÉe par le biais d'un filtrage et d'un tri de gouttes satellites
Abstract
(EN)
Improved systems and methods are provided herein for passively filtering out droplets of different size such as satellite droplets from the generation of primary droplets and use these satellite droplets as the source for monodispersed production of submicron emulsions. The systems and methods described use active flow control to sort droplets of different size into desired collecting zones and use conventional shearing principles, and, as a result, provide 100% filtration of satellite droplets regardless of size differences.
(FR)
Les systèmes et procédés améliorés proposés permettent de filtrer passivement des gouttelettes de différentes tailles, comme par exemple des gouttelettes satellites, à partir de la génération de gouttelettes principales, et utilisent ces gouttelettes satellites en tant que source pour la production d'émulsions inférieures au micron monodispersées. Les systèmes et procédés décrits utilisent une régulation de flux active pour trier des gouttelettes de différentes tailles à l'intérieur de zones de collecte souhaitées, et utilisent des principes de cisaillement conventionnels. Ils procurent ainsi une filtration à 100 % de gouttelettes satellites sans tenir compte des différences de taille.
