S. aureus adhesion and growth on nanodiamond (ND)-coated selective laser melted titanium (ND) substrata (ND-SLM-Ti). Live/Dead staining of S. aureus growth on (a) uncoated SLM-Ti, (b) 0.0075% w/v ND, (c) 0.75% w/v and (d) 7.5% w/v ND-coated SLM-Ti substrates after 18 h of incubation. (e) S. aureus density on the uncoated SLM-Ti and SLM-Ti coated with 0.075–0.75–7.5% w/v ND quantified from Live/Dead fluorescent images after 18 h of incubation. The S. aureus density is expressed as average cell number per mm2 and indicated as mean ± standard deviation, n = 3. p < 0.01. SEM micrographs of S. aureus adhesion on (f) uncoated SLM-Ti, (g) 0.0075% w/v ND, (h) 0.75% w/v and (i) 7.5% w/v ND-coated SLM-Ti substrates after 18 h of incubation (Mag. 1000×, scale bar 50 µm; insert Mag. 30,000×, scale bar 5 µm).
