SEM images of differently functionalized Ti substrates after exposure to the S. aureus suspension (107 cfu mL−1) in PBS for 8 h: (a) pristine Ti, (b) DA-Ti, (c) PLL/Hep-Ti, (d) CH-Ti, and (e) CH-MTX-Ti. (f) The number of S. aureus (cfu) in culture normalized to the area of the substrates after the bacterial cell culture interacted with various Ti substrates for 24 h. denotes significant differences compared to substrates modified with the CH-MTX-Ti group. The error bars represent the standard deviations calculated from three independent experiments.
