Abstract
In the present study we have investigated the effect of zinc oxide (ZnO) nanoparticles on the fiber diameter, fiber morphology, antibacterial activity, and enhanced cell prolifer- ation of the electrospun polycaprolactone (PCL) non-woven membrane. The effect of the ZnO nanoparticle concentration on the fiber diameter and fiber morphology was investigated using a scanning electron microscope (SEM). Fourier trans- form infraredspectroscopy(FT-IR)analysis was carried out to determine the nature of the interaction between the PCL and the ZnO nanoparticles. We also investigated the mechanical stability and antibacterial activity of the fabricated material. Interestingly, the membranes with ZnO nanoparticles showed enhanced mechanical stability, antibacterial properties, fibro- blast proliferation, and improved metabolic activity of the cells. Further, this is the first report regarding the ability of a biomaterial containing ZnO nanoparticles to enhance cell proliferation.
