Photoinitiator-free visible-light bioprinting: minimising radical-induced oxidative stress and DNA damage in gelatin hydrogels

Light-mediated crosslinking of polymers is widely employed in the preparation of hydrogels for biofabrication and tissue engineering, since photo-crosslinking enables the spatiotemporal control over the gelation processes.

Light-mediated crosslinking of polymers is widely employed in the preparation of hydrogels for biofabrication and tissue engineering, since photo-crosslinking enables the spatiotemporal control over the gelation processes. Nevertheless, a critical bottleneck persists: most…
