Antibacterial nanospike surface obtained by high-fluence Ar+ bombardment of nanostructured titanium

In order to find the ways of giving antibacterial properties to implants, a homogeneous nanospike morphology on titanium surface was formed by deformation nanostructuring followed by bombardment by high-fluence Ar+ ions. Taking account of the fact that antibacterial properties were studied on an example of E. coli bacteria, nanospikes having a height of 200 nm and spacings about 100 nm were formed. Studies using fluorescence microscopy have shown that when E. coli bacteria are applied to a smooth titanium surface, the bacteria form clusters of cells similar to the biofilm structure. In contrast to this, clusters of E. coli are not observed on the nanospike surface, i. e., it has antibacterial properties.
