Abstract We describe preparation, characterization and cytocompatibility of nanodiamond (ND) dispersed in poly (ε-caprolactone) (PCL) based nanofibrous scaffold. The results show that this unique scaffold potentially provides essential properties for wound healing by enhancing proliferation of epithelial cells, in addition to restricting the microbial activities. Electrospinning technique was used to fabricate and develop PCL-NDs nanocomposite scaffold. The developed nanocomposites were characterized for morphology, thermal, surface and biological properties. The incorporation of ND into the PCL matrix resulted in better moisture management and higher thermal stability. Transmission electron microscopy images and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy showed existence of ND particles on the surface of the nanofibers. The aggregation of ND particles increased with the increase in their concentration in nanofiber. The developed scaffolds showed no cytotoxicity and, due to improved hydrophilicity, better cellular activities with Chinese hamster ovarian (CHO) cells, 43%, 38% and 22% more cell proliferation for PCL-5% ND for 1, 3- and 7-days incubations in compare with PCL. Furthermore, Staphylococcus aureus (S. aureus) showed significantly less affinity to the scaffold surface with the increase in ND concentration, ~56% less for PCL-5% ND in compare with PCL, indicating that such ND dispersed nanofibrous scaffold maybe asuitable choice for complex wound management.
