چکیده انگلیسی
Novel biodegradable hydrogels by photocrosslinking macromers based on chitosan derivative are reported. Photocrosslinkable macromers, a water-soluble (methacryloyloxy) ethyl carboxyethyl chitosan were prepared by Michael-addition reaction between chitosan and ethylene glycol acrylate methacrylate. The macromers were characterized by Fourier transform infrared spectroscopy, 1H NMR and 13C NMR. Hydrogels were fabricated by exposing aqueous solutions of macromers with 0.1% (w/v) photoinitiator to UV light irradiation, and their swelling kinetics as well as degradation behaviors was evaluated. The results demonstrated that the degradation rates were affected strongly by crosslinking density. The hydrogel was compatible to Vero cells, not exhibiting significant cytotoxicity. Cell culture assay also demonstrated that the hydrogels were good in promoting the cell attachment and proliferation, showing their potential as tissue engineering scaffolds.
