Fig. 5: Investigation into mechanical strengthening mechanisms during PLCL degradation.
From: Mechanically robust neuroprotective stent by sequential Mg ions release for ischemic stroke therapy

A Staged-radial force of PLCLxMS stents measured after immersion for 7, 14, 28 and 56 days. B FTIR spectra of PLCL5MS stents after immersion for 7 days (Fast) and 56 days (Stable). C Schematic diagram illustrating experiments and conjectures to investigate the reinforcement mechanism of Mg2+ during PLCL degradation (Created in BioRender123). D Hardness of the PLCL surface after immersion in various solutions. E FTIR spectra of the PLCL surface post-immersion. F, G High-resolution O1s XPS spectra of PLCL following immersion. Source data and exact P values are provided as a Source data file. One-way analysis of variance (ANOVA) with a Tukey/Games-Howell post hoc test for multiple comparisons. Sample size: n = 4 biologically independent replicates. *P < 0.05, PLCL vs. Deioinzed water group or PLCL vs. MgSO4 solution group; ### P < 0.001, Deioinzed water vs. MgSO4 solution group. Data are presented as mean values ± SD.
