A modified titanium surface that improved pre-osteoblast (bone-forming cell) adhesion through anodization method which created TiO2 nanotube array, and electrodeposition method which later coated with graphene oxide (GO) was studied. The solution of GO was used at the concentrations of 150 μg/ml and 200 μg/ml during electrodeposition process. The samples with GO coating at the concentration of 200 μg/ml were observed clearly a morphology of the GO coating on the samples using scanning electron microscopy. On anodized titanium the TiO2 nanotube array was appeared with the diameter at about 50 nm. The investigation of elements with energy dispersive X-ray spectrometry confirmed a presence of carbon and oxygen after surface modifications. The coated samples with GO had a significant increase of elemental percentage of carbon. The anodized titanium had the higher of oxygen than conventional titanium. The study of cell adhesion and spreading with pre-osteoblast cells was performed with a standard cell culture and cell staining after four hours. The results indicated that GO coating on conventional titanium improved significantly the cell density on the samples. Pre-osteoblast cells were well spread on GO coatings on both conventional and anodized titanium.
