Aninwene II GE, Yao C, Webster TJ. Enhanced osteoblast adhesion to drug-coated anodized nanotubular titanium surfaces. Int J Nanomedicine. 2008;3(2):257–264.
There is a mistake in the Drug coating section of the Materials and methods. In the paper it is written as follows:
“For simple physical adsorption, 120 μL of either penicillin/streptomycin (Hyclone, Logan, UT, USA; 5 μg/mL) or dexamethasone (Sigma, St. Louis, MO, USA; 5 μg/mL) solutions were placed onto each unanodized or anodized titanium for 3 days at room temperature.”
But the text should be written as:
“For simple physical adsorption, 120 μL of either penicillin/streptomycin (Hyclone, Logan, UT, USA; 6.25 mg penicillin and 10 mg streptomycin per mL) or dexamethasone (Sigma, St. Louis, MO, USA; 5 mg/mL) solutions were placed onto each unanodized or anodized titanium for 3 days at room temperature.”
