Title
(EN) MULTIPLE EMULSIONS AND TECHNIQUES FOR THE FORMATION OF MULTIPLE EMULSIONS
(FR) ÉMULSIONS MULTIPLES ET TECHNIQUES DE FORMATION D'ÉMULSIONS MULTIPLES
Abstract
(EN)
Multiple emulsions and techniques for the formation of multiple emulsions are generally described. A multiple emulsion, as used herein, describes larger droplets that contain one or more smaller droplets therein. In some embodiments, the larger droplet or droplets may be suspended in a carrying fluid containing the larger droplets that, in turn, contain the smaller droplets. As described below, multiple emulsions can be formed in one step in certain embodiments, with generally precise repeatability, and can be tailored in some embodiments to include a relatively thin layer of fluid separating two other fluids.
(FR)
La présente invention concerne des émulsions multiples et des techniques de formation d'émulsions multiples. Une émulsion multiple telle que celle utilisée ici présente de grosses gouttelettes qui contiennent une ou plusieurs petites gouttelettes. Dans certains modes de réalisation, la ou les grosses gouttelettes peuvent être en suspension dans un fluide porteur contenant les grosses gouttelettes qui, elles-mêmes, contiennent les petites gouttelettes. Conformément à la description, des émulsions peuvent être formées en une étape dans certains modes de réalisation, avec une répétabilité généralement précise, et peuvent être préparées sur mesure dans certains modes de réalisation pour inclure une couche relativement mince de fluide séparant deux autres fluides.
