a The chemical structure of the βCD-Ad-Fc gels; x, y, and z indicate the amount (mol%) of different units. b Photograph of the βCD-Ad-Fc gel. c Self-healing of the βCD-Ad-Fcp gel. a 4 × 4 × 4 mm3 cubic piece of βCD-Ad-Fc gel was cut in half with a razor edge, and the two cut edges were held together again. Within 2 h under wet conditions, the gel pieces adhered to form one gel. d Schematic illustration of the shape-memory mechanism.
