Preparation of HA Hydrogel by Click Chemistry

Article Preview

Abstract:

"Click chemistry" was used in this paper to get a novel hyaluronic acid (HA) hydrogel by modified HA molecules' side chains with azide and alkynyl groups to perform "Click" reaction. The HA hydrogel can be achieved "in situ" injection gel. The properties of the HA hydrogel can be controlled by controlling the amount of alkynyl and azide groups on side chains to achieve controllable HA hydrogel by HA molecular design. The reactant, product and hydrogel were characterized by 1H NMR, FTIR and morphology observation to determine the processes of reaction and can hydrogel formation.
