Fabrication of a shape memory hydrogel based on imidazole–zinc ion coordination for potential cell-encapsulating tubular scaffold application
Abstract
A dipole–dipole reinforced copolymer hydrogel was synthesized by the one-step photopolymerization of vinylimidazole (VI) and acrylonitrile (AN) comonomer in the presence of a polyethylene glycol-based crosslinker. The mechanical properties of PVI–AN gels were tremendously increased by only chelating several mmol L−1 zinc ions, which was shown to firmly lock the temporary shape of the gel. Extraction of zinc ions by a complexing agent could facilitate the recovery of a permanent shape, and the memory behavior was reversible. The PVI–AN hydrogels supported the growth of L929 cells. The cell-seeded flat hydrogel sheet was folded into a temporary tubular scaffold and fixed in a culture medium containing 5 mmol L−1 zinc ions. After unfolding the tube, the exposed L929 cells were shown to adhere well on the surface of the gel. It is anticipated that this cell-loaded SM hydrogel could be fixed to a desired shape in vitro by small numbers of zinc ions for a potential implantable tissue engineering scaffold.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
