The bacterial studies of nanocrystalline diamond
Original language description
In this study we investigated the potential antibacterial properties of diamond. We tested the samples of nanocrystalline diamond (NCD) lm treated by either oxygen or hydrogen plasma and nano-diamond powder (DP). Silica glass and cop- per were used for negative and positive control samples, respectively. Escherichia coli and Bacillus subtilis were used as representatives of Gram negative and Gram positive bacteria, respectively. The outputs of pilot experiments indicate that the antibacterial e ect of NCD is limited to the direct contact of bacteria with its surface. The preliminary results of dehydrogenase activity assay and tests on liquid and solid media imply that the potential antibacterial properties of NCD are probably short time and distance limited due to lack of free diffusion. This observation could be the result of death cell biomass deposition on thin layers which will be further discussed. The inence of DP on cells growing in liquid culture is investigated as an alternati
