Notes:
Novel Poly(l-lactic acid) (PLLA)/ Multi-walled carbon nanotubes (MWNTs)/hydroxyapatite (HA) nanofibrous scaffolds with high porosity and well-controlled porearchitectures were prepared via electrospinning techniques. The structure, morphology, molecularweight change of the scaffolds were investigated using scanning electron microscopy (SEM). Theresults noticed that the average diameter of hybrid nanofiber was similar to that of PLLA/HA fiber,but the surface of hybrid fibers was much coarser because of the introduction of MWNTsnano-particles. The biocompatibility of the scaffold has been investigated by human Dental PulpStem Cells (DPSCs) cell culture on the scaffold. The preliminary results showed that cells werewell adhered and proliferated on the hybrid scaffolds as well as PLLA/HA fibers. Based on theexperimental observations, the aligned nanofibrous PLLA/ MWNTs /HA scaffold could be used asa potential candidate scaffold in dental tissue engineering
