3D Printed Bioactive PLGA Dermal Scaffold for Burn Wound Treatment.

ABSTRACT: Burn injury represents a major global public healthcare problem and has a significant health-economics impact. In this study, we report on a 3D printed poly(lactic-co-glycolic acid) (PLGA) dermal scaffold containing bioactive PLGA for burn wound healing. Bioactive brush copolymers containing pendant side chains of PLGA and PEGylated Arg-Gly-Asp tripeptide (RGD) or hyaluronic acid (HA) were synthesized by ring-opening metathesis polymerization (ROMP). These copolymers exhibited good thermal stability for material processing using melt-extrusion-based methods. The copolymers were blended with commercial PLGA, extruded into filaments and 3D printed using fused filament fabrication (FFF) methods with incorporated porosities. The 3D printed scaffolds demonstrated good biocompatibility in
