3D printing of artificial skin patches with bioactive and optically active polymer materials for anti-infection and augmenting wound repair

A printable ink composed of a photoactive cationic conjugated poly(phenylene vinylene) derivative (PPV) and gelatin/alginate/hyaluronic acid is developed for 3D printing artificial skin patches. This patch shows excellent photodynamic therapy-based anti-infection superiority and outstanding bioactivity to facilitate wound repair. This study contributes to design new conjugated polymer inks for manufacturing functional skin patches.
