Characterization of the fibrous membranes. (A–D) SEM images and gross photographs (insert) of different fibrous membranes. (E–H) Diameter distribution analysis of different fibrous membranes. Scale bars = 100 μm. (A,E) PLGA, (B,F) nSi-PLGA, (C,G) DMOG-PLGA, (D,H) DMOG/nSi-PLGA. (I) FTIR spectra of the fibrous membranes. (J) Stress-strain curve of different fibrous membranes. (K,L) Cumulative release curves of DMOG and silicon from DMOG/nSi-PLGA fibrous membrane.
