Alkaline phosphatase activity of the cells cultured on titanium control, NT-Ti, and AgNP-NT-Ti.
Notes: Data are presented as mean standard deviation (n = 3, *P < 0.05, “0.01 mM” versus “Titanium”; #P < 0.05: the same sample versus the one at the previous time.
Abbreviations: NT-Ti, titanium foil sample with hydrogen titanate nanotube layer; AgNP, silver nanoparticle; AgNP-NT-Ti; AgNP-filled nanotube layer on the titanium foil surface; ALP, alkaline phosphatase; OD, optical density.
