Document Type and Number:
WIPO Patent Application WO/2021/208987
Kind Code:
A1
Abstract:
A first aspect of the invention refers to a method for producing a hydrogel microsphere, the method comprising the steps of: a. generating by means of a capillary a droplet of controlled size of a first fluid in a gaseous phase, b. dispensing said droplet of a first fluid into a recipient comprising a second fluid, wherein the first fluid is immiscible with the second fluid and wherein the density of the second fluid is lower than the density of the first fluid, c. contacting the droplet of the first fluid with the second fluid, thereby producing a hydrogel microsphere, d. recovering the hydrogel microsphere from the second fluid for storage. A second aspect of the invention is directed to a hydrogel microsphere obtainable by the method according to the first aspect of the invention. A further aspect of the invention refers to a system for producing a hydrogel microsphere according to any of the second and third aspect.
