Contact angles of bacterial cells with material surfaces. (A) Observation of bacterial adhesion and morphology of S. aureus on the unmodified titanium surface, TNT-118 and TNT-73 using scanning electron microscopy with samples tilted at 25°. (B) Determination of cell contact angles between the cell wall and the surface for each sample type. Statistically significant differences are indicated as **for p < 0.01 and ****for p < 0.0001.
