Bacterial growth and growth inhibition on samples with modified surfaces. (A) Comparison of bacterial CFU counts after 24 h incubation on different sample types (a glass slide as the control, the unmodified Ti sample, TNT-118, TNT-73). Statistically significant differences are indicated as *for p < 0.05 and **for p < 0.01. The differences between the nanostructured samples and a glass slide were similar as for bare Ti. (B) Percentage of relative bacterial growth inhibition on the samples with modified surfaces after 24 h. (C) Growth folds for different surfaces.
