Changes in bacterial morphology on the titanium disc surface; NP, P2, and P10. (A) Field-emission scanning electron microscopy images of bacteria adherent to titanium disc following NP, P2, and P10 (scale bar = 1 µm). (B) Transmission electron microscopy images of bacteria adherent to titanium disc following NP, P2, and P10 (scale bar = 500 nm, scale bar = 1000 nm).
