Synthesis and characterization of RSD-MS. (A) Microscopic images of SD-MS and RSD-MS. (B) Particle size distribution of SD-MSs and RSD-MSs. The lower sections display lower magnification images (scale bars: 500 μm) in the upper sections (scale bars 100 μm). (C) 1H NMR spectrogram of SD-MSs and RSD-MSs. (D) SEM images of SD-MS and RSD-MS. The lower sections display higher magnification sections (scale bars: 50 μm) of the areas highlighted by white boxes in the upper panels (scale bars 100 μm). (E) Pore size of SD-MSs and RSD-MSs. (F) The swelling ratio of SD-MSs and RSD-MSs in PBS at 37 °C. (G) In vitro degradation curves of SD-MSs and RSD-MSs in PBS and protease K solution at 37 °C.
