A Scanning electron microscopy (SEM) images of the different samples. Scale bars: 20 μm. B Element mapping images of the GelMa/Mg/DMF MS. Scale bars: 20 μm. C Energy dispersive spectroscopy (EDS) spectrum of the GelMa/Mg/DMF MS. D X-ray diffraction (XRD) patterns of the different samples. E Mg ion release of GelMa/Mg/DMF MS detected by inductively coupled plasma-optical emission spectrometry (ICP) (n = 3 independent experiments). F Microsphere morphology of GelMa/Mg/DMF MS under light microscopy at different times of degradation (schematic diagram is shown in the upper right corner, created with BioRender.com). Scale bars: 20 μm. G Detection of dimethyl fumarate (DMF) release via UV-vis spectroscopy (n = 5 independent experiments). H Detection of hydrogen release from materials by reduction of methylene blue. I Detection of the total antioxidant capacity of GelMa/Mg/DMF MS via the 3, 3’, 5, 5’-tetramethylbenzidine (TMB) method. The data are presented as the means ± SD. Source data are provided as a Source Data file.
