(Top-left) The electrophoretic method for fabrication of MSNs-NH2/PLLA/PCL scaffold for delivery of dexamethasone. (Top-right) SEM images showing the effect of varying the voltage in the electrophoretic method on the porosity of MSNs-NH2/PLLA/PCL scaffolds. (A) SEM image of microstructure of scaffold; (B) fabrication process of the scaffold at 1 Volt, (C) 3 Volts and (D) 5 Volts. (Bottom) Osteocalcin expression analysis for the modified and unmodified mesoporous SNMs showing the effect of SNMs on the differentiation process of bone stem cells after (A, C) 14 days and (B, D) 21 days.
