Abstract
Hyaluronate functionalized with dihydrazide is provided and may be cross-linked. A method for producing hyaluronate functionalized with dihydrazide includes mixing hyaluronate and dihydrazide in aqueous solution, then adding carbodiimide so that the hyaluronate and dihydrazide react to form functionalized hyaluronate.
