Interpenetrating networks hydrogels based on hyaluronic acid for drug delivery and tissue engineering

Abstract

ABSTRACTThere are several techniques for preparing hydrogel biomaterials. Among these techniques, preparation of interpenetrating polymer networks hydrogel (IPNs) has been more interested during last years. IPNs are fabricated by the incorporation of monomers or polymeric chains in hydrogel network. Natural polymers such as hyaluronic acids have some advantages such as biocompatibility, biodegradability and non-toxicity. In this review, we would have a brief view to the interpenetrating polymer networks hydrogel based on hyaluronic acids and its applications as a drug delivery system and tissue engineering applications.
