A dual drug-loaded system is a promising alternative for the sustained drug release system and skin tissue engineering. In this study, a natural sodium montmorillonite (Na-MMT) modified by cetyl trimethyl ammonium bromide (CTAB) was prepared as a carrier to load a model drug - amoxicillin (AMX), the modified organic montmorillonite (CTAB-OMMT) loaded with AMX was marked as AMX@CTAB-OMMT and was subsequently incorporated into polyester-urethane) urea (PEUU) and gelatin hybrid nanofibers via electrospinning, resulting in a new drug-loaded nanofibrous scaffold (AMX@CTAB-OMMT-PU75). The scanning electron microscopy (SEM) result showed that the fiber morphology did not change after the embedding of AMX@CTAB-OMMT. Meanwhile, there was a significant increase of mechanical properties for PEUU/Gelatin hybrid nanofibers (PU75) after the incorporation of AMX@CTAB-OMMT and CTAB-OMMT. Importantly, AMX@CTAB-OMMT-PU75 nanofibers showed a kind of sustained drug release property which could be justified reasonably for the controlled release of AMX depending on the various application. The sustained release property could be identified roughly by the result of antibacterial test. The anaphylactic reaction test proved that there was no any anaphylactic reaction or inflammation on the back of rat for AMX@CTAB-OMMT-PU75 nanofibers. Consequently, the prepared drug-loaded AMX@CTAB-OMMT-PU75 nanofibrous scaffold is a promising candidate for application in the skin tissue engineering field and controlled drug release system.
