CAPSULES WITH A HYDROGEL MATRIX
Disclosed herein is a method for generating capsules with a hydrogel matrix, the method comprising the steps: Providing in a first chamber (4) a dispersed aqueous phase, the dispersed aqueous phase comprising water and a hydrogel matrix-forming agent, wherein the hydrogel matrix-forming agent is configured to form a hydrogel matrix upon exposure to a gelation inducer; Providing in a second chamber (5) a continuous oil phase, the continuous oil phase comprising oil and at least one first surfactant; wherein the first chamber and the second chamber are fluidic connected by one or more channels (10), preferably by micro-channels; the method further comprising: Guiding the dispersed aqueous phase from the first chamber (4) through the one or more channels (10) into the second chamber (5) to form an emulsion or dispersion of the dispersed aqueous phase in the continuous oil phase; Exposing the hydrogel matrix-forming agent to a gelation inducer to form capsules with a hydrogel matrix..
