NCD films were shown to be well biocompatible with tissue cells; however their possible antibacterial properties have been much less investigated.For our studies, we grew NCD films by chemical vapour deposition method on glass substrates and treated them by hydrogen, oxygen and CF4 plasma to achieve different wetting angles (70°, 5°, 100°, respectively). Apart from wetting angle measurements, the surface properties of NCD films were further examined by scanning electron microscopy, Fourier transform infrared spectroscopy, Raman spectroscopy and X-ray photoelectron spectroscopy.We present two methods of bacterial biofilm cultivation suitable for studying the bacterial growth on solid surfaces, which we will use for testing of possible antibacterial properties of NCD films.
