Smart pH/magnetic sensitive Hericium erinaceus residue carboxymethyl chitin/Fe3O4 nanocomposite hydrogels with adjustable characteristics

A smart hydrogel with pH/magnetic dual sensitivity was synthesized by in-situ synthesis of Fe3O4 inside carboxymethyl chitin hydrogel matrix prepared from Hericium erinaceus residue. The structure, pH/magnetic sensitivity, swelling and drug release behavior of the prepared hydrogels were investigated. The results showed that Fe3O4 nanoparticles were successfully synthesized and uniformly distributed within the hydrogels. The prepared hydrogels...
