First original post here! We have developed a photoinitiating system that can crosslink hydrogels upon CW red light without leaving any colour of a photoinitiator. It's cell-friendly (FDA-approved dye). And we can do it even through 5 mm of biotissue

Traceless Photopolymerization with Non‐Pulsed Red Light Enables 3D‐Printable Cell‐Laden Hydrogels
The paper presents a red-light-induced polymerization process, initiated by the FDA-approved dye methylene blue and the cytocompatible co-initiator triethanolamine, for fabricating hydrogels. This ph...
