在目前的工作中，作者产生了钛表面的TiO_2纳米管涂层，并研究这些层与MoO_2的电化学填充。作者证明，使用潜在的循环技术，可以生成均匀的MoO涂层。通过改变循环次数可实现可控和可变的涂层厚度。可以获得从几纳米到完全填充纳米管层的厚度。使用热处理将沉积的非晶MoO（x）相转化为MoO微晶。然后使用金黄色葡萄球菌、大肠杆菌和铜绿假单胞菌菌株研究这些负载MoO的纳米管层的抗微生物特性。作者发现，结晶MoO在TiO_2纳米管上的组合显示出优异的抗菌性能。
In the present work, the authors produce a Ti surface with a TiO₂ nanotube coating and investigate the electrochemical filling of these layers with MoO₃. The authors demonstrate that using a potential cycling technique, a homogenous MoO₃ coating can be generated. Controllable and variable coating thicknesses are achieved by a variation of the number of cycles. Thicknesses from a few nanometers to complete filling of the nanotube layers can be obtained. A thermal treatment is used to convert the as-deposited amorphous MoO(x) phases into MoO₃. These MoO₃ loaded nanotube layers were then investigated regarding their antimicrobial properties using strains of Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. The authors found that the combination of crystalline MoO₃ on TiO₂ nanotubes shows excellent antimicrobial properties.
