US Patent:

20120000777, Jan 5, 2012

Filed:

Jun 6, 2011

Appl. No.:

13/154248

Inventors:

Robin L. Garrell - Los Angeles CA, US
Alexander K. Tucker-Schwartz - Los Angeles CA, US
Heather Shepherd - Oakland CA, US
Debalina Chatterjee - Hollywood CA, US

Assignee:

THE REGENTS OF THE UNIVERSITY OF CALIFORNIA - Oakland CA

International Classification:

C25B 15/00
B01F 3/08

US Classification:

204451, 204601

Abstract:

The present invention generally relates to double emulsion droplet compositions, polymer particles that can be formed from such double emulsion droplet compositions, and to methods and apparatuses for making such compositions and particles. A double emulsion generally describes larger droplets that contain smaller droplets therein. These double emulsion droplet compositions can be used to create a variety of materials including polymer particles and polymeric shells and are further useful for encapsulating a variety of species including catalyst compounds and pharmaceutical agents. The double emulsion droplet compositions disclosed herein are readily formed using planar droplet (“digital”) microfluidic devices without channels, and either air or an immiscible liquid as an ambient medium.
