SEM micrographs of GO coated on HA-ATi in a layer-by-layer deposition method on (a) HA-ATi or GO0 and HA-ATi coated with various GO concentrations. (b) GO1; (c) GO2; (d) GO3; (e) GO4. Inset micrographs show ImageJ analysis of the figures; (f) a comparison of HA intensity, derived from ImageJ analysis. The value was calculated using one-way ANOVA; , . Scale bars are 5 μm.
