  • Crosslinking of hyaluronan solutions and nanofiberous membranes made therefrom
    Patent number: 7323425
    Abstract: A method for producing a non-chemically crosslinked hyaluronan is provided which involves contacting a sample of hyaluronan with an acidic solvent/water mixture for a period of time and at a temperature sufficient to effect crosslinking, wherein the acidic solvent/water mixture has a content of a solvent sufficient to prevent dissolution of said hyaluronan and wherein the solvent is miscible with water, and an amount of an acid sufficient to effect crosslinking of the hyaluronan, and the crosslinked, water resistant non-woven hyaluronan resulting therefrom.
