a Photographs of the SF-1nMgO scaffolds subjected to various mechanical modes, which rapidly recovered their initial shape when triggered by water. b1-b3 Representative compressive stress-strain curves of the SF, SF-1nMgO and SF-3nMgO scaffolds. c Compressive modulus of the SF, SF-1nMgO and SF-3nMgO scaffolds during immersion in SBF solution after different time lengths (0, 14, 28 days). d Compressive stress-strain curves of the SF-1nMgO scaffolds with 30% strain for 5 cycles. e Compressive fatigue behaviour of the SF-1nMgO scaffolds. Values in (c) represent the mean ± SD. Statistical difference was determined by two-tailed unpaired Student’s T-test between two groups. One-way analysis of variance (ANOVA) with a Tukey’s post hoc test for multiple comparisons. n = 4 independent replicates from three samples. Source data and exact P values are provided as a Source data file. (ns: P > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001).
