Cytotoxicity assessment of the optimized EM/AgNPs nanocomposite. Fluorescence microscopy images of GFP transgenic fibroblast attachment on the EM/PD films immersed in AgNO3 solutions of different concentrations: (A) 50 mM; (B) 10 mM; (C) 1 mM; (D) 100 μM; (E) 50 μM; (F) 30 μM; (G) 10 μM; and (H) 0 μM and (I) on EM. (J) Viability of fibroblasts cultured on EM, EM/PD and EM/AgNPs. The values are shown as the mean ± SD (n = 3).
