Development of a ۳D-printable hydrogel system based on a Zwitterionic polymer

This study presents the development of a ۳D-printable hydrogel system that combines PDMAPS with alginate and gelatin. The hydrogel was fabricated through sequential UV-initiated photopolymerization of PDMAPS and ionic crosslinking of alginate with calcium chloride. FTIR spectroscopy confirmed the successful synthesis and crosslinking of components, while SEM analysis verified the preservation of printed structures. Through optimization of component concentrations and crosslinking parameters, a printable hydrogel system was achieved that integrates the anti-fouling properties of zwitterionic polymers with the biocompatibility of natural polymers, offering potential applications in tissue engineering.
