abstract = {Biocompatible polymers that form thermoreversible
supramolecular hydrogels have gained great interest in
biomaterials research and tissue engineering. When favorable
rheological properties are achieved at the same time, they
are particularly promising candidates as material that allow
for the printing of cells, so-called bioinks. We synthesized
a novel thermogelling block copolymer and investigated the
rheological properties of its aqueous solution by
viscosimetry and rheology. The polymers undergo
thermogelation between room temperature and body
temperature, form transparent hydrogels of surprisingly high
strength (G′ > 1000 Pa) and show rapid and complete shear
recovery after stress. Small angle neutron scattering
suggests an unusual bicontinuous sponge-like gel network.
Excellent cytocompatibility was demonstrated with NIH 3T3
fibroblasts, which were incorporated and bioplotted into
predefined 3D hydrogel structures without significant loss
of viability. The developed materials fulfill all criteria
for future use as bioink for biofabrication.},
