Abstract:  
Abstract Currently implanted titanium and titanium-based alloys do not possess antibacterial properties. The objective of the present in vitro study was to modify currently implanted titanium by shot peening to implement nanoscale surface features that can reduce bacteria function without the aid of pharmaceutical agents. Results demonstrated significantly lower functions of bacteria on shot peened titanium. In this manner, aside from the well documented mechanical properties, this study provided evidence that infection can be reduced on shot peened titanium and, thus, should be further explored for orthopedic applications.
