Click chemistry for 3D bioprinting.

Bioinks are employed in the fabrication of 3D scaffolds containing cells and macromolecules that can be applied in regenerative medicine. The use of such bioinks facilitates the controlled introduction and localization of macromolecules, bioactives and cells for the biofabrication of living tissues. To enable the successful preparation of the bioinks, strategies involving the use of so-called cross linkers, which may be ionic, chemical, photo-
