Fig. 4From: Iodine-doped TiO2 nanotube coatings: a technique for enhancing the antimicrobial properties of titanium surfaces against Staphylococcus aureusVisual characteristics of iodine-doped TiO2 nanotube-coated titanium plate. Appearance of the iodine-doped TiO2 nanotube-coated titanium plate. After the electrophoretic deposition of iodine onto the TiO2 nanotube arrays, a light-yellow granular coating was observed on the surface of the titanium plateBack to article page
