Abstract :In the present work, 3D-printed wound dressings containing different amounts of Centella Asiatica extract were synthesized via dual-crosslinking method. Methacrylic anhydride modified gelatin insert ignore into journalissuearticles values(Gel-MA); and pectin insert ignore into journalissuearticles values(Pec); were chosen as the base material for dressings. A dual crosslinked network was formed with Gel-MA photo-crosslinking using Irgacure 2959 and Pectin insert ignore into journalissuearticles values(Pec); psychical-crosslinking using Ca++ ions. Meanwhile, the developed dual-crosslinked hydrogel dressings were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and mechanical, swelling, in vitro degradation as well as ex vivo bioadhesion tests. It has been observed that the preapred dressings provide good bioadhesion on the chicken skin. Moreover, MTT assay revealed cell viability of Gel-MA/Pec hydrogel dressings containing Centella Asiatica extract. The results presented the dressings as a promising biomaterial to be used for wound healing purposes, which should be further investigated in future.
