Cell proliferation for Day 1, Day 3 and Day 5, on titanium control, NT-Ti, AgNP-NT-Ti, and AgNO3-NT-Ti.
Notes: Data are presented as mean plus standard deviation (n = 3, *P < 0.05, “0.01 mM” vs “Titanium”; #P < 0.05: the same sample vs 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; AgNO3-NT-Ti, titanium foil with a AgNO3-filled hydrogen titanate nanotube layer on the surface; OD, optical density.
