    Abstract: There is provided a process for preparing a HA cryogel, the process comprising the steps of combining HA, a cross-linking agent and a solvent to form a solution, freezing the solution before the formation of less than 10% of the cross-linking bonds of the cross-linked HA cryogel formed and thawing the solution. An HA cryogel is also provided, in particular an HA cryogel obtained from this process.
