Abstract
The present invention relates to a process for producing a composition comprising an aqueous medium and, disposed in the aqueous medium, a first volume of a first hydrogel, which process comprises: (i) providing a composition comprising a first hydrophobic medium and, disposed in the first hydrophobic medium, a first volume of a first hydrogel; (ii) disposing a volume of an aqueous composition comprising a hydrogel compound around the first volume of the first hydrogel; (iii) allowing the aqueous composition comprising the hydrogel compound to form a gel and thereby forming a hydrogel object, which hydrogel object comprises the first volume of the first hydrogel and a second volume of a second hydrogel, which second volume of the second hydrogel is disposed around the first volume of the first hydrogel; and (iv) transferring the hydrogel object from the first hydrophobic medium to an aqueous medium and thereby producing the composition comprising the aqueous medium and, disposed in the aqueous medium, the first volume of the first hydrogel. The invention further provides a hydrogel object, which hydrogel object comprises a first volume of a first hydrogel and a second volume of a s…
