A Generalizable Strategy for the 3D Bioprinting of Hydrogels from Nonviscous Photo-crosslinkable Inks

Adv Mater. 2017 Feb;29(8). doi: 10.1002/adma.201604983. Epub 2016 Dec 16.


An in situ crosslinking strategy is used for 3D bioprinting of nonviscous photo-crosslinkable hydrogels. This method can be generalized to various photo-crosslinkable formulations, maintaining high embedded cell viability and tunable cell behavior. Heterogeneous and hollow filaments can be printed using this strategy, allowing fabrication of complex engineered cell-laden constructs.
