can be adjusted by varying the molar fraction of guest molecules grafted on the PVA
backbone. Due to the dynamic host-guest complexation, the hydrogel is able to
recover quickly under ambient condition, and its mechanical properties can restore
its original state within 1 min after being damaged. Because of the biocompatibilities
of PVA polymers, bile acids, and β-CDs, this hydrogel exhibited high
cytocompatibility and good blood compatibility which had been proven by MTT
cytotoxicity assay and hemolysis assessment. In summary, this host-guest
