Measurement of biofilm coverage. (A) S. aureus biofilm coverage of samples with four different surface types (glass slide, the unmodified Ti, TNT-118, TNT-73). Results are expressed as the percentage of surface coverage. Statistically significant differences are indicated as *for p < 0.05. The differences between the nanostructured samples and glass slide were similar as for bare Ti. The percentage of surface coverage was 89.2 (± 2.0) on glass slide, 84.0 (± 8.8) on unmodified Ti, 70.4 (± 4.5) on the TNT-118 and 67.8 (± 4.2) on the TNT-73. (B) S. aureus biofilm formed after an overnight incubation on different surfaces (left). The evaluation of surface coverage using the brightness threshold parameter in the ImageJ software (right).
