  • CONTROLLING FREEZE-DRYING OF A HYDROGEL
    Publication number: 20220348882
    Abstract: The present disclosure relates to a method for controlling freeze-drying of a hydrogel wherein the method comprises adjusting the residual water content of the freeze-dried hydrogel, and to a freeze-dried hydrogel composition comprising nanoscale cellulose and a at least one biomolecule selected from an oligosaccharide or a disaccharide. The present disclosure further concerns the use of the freeze-dried hydrogel composition for cell culturing, a cell culturing scaffold as well as a process for manufacturing a reconstituted hydrogel.
