## Description

- description: Fine-particle bombardment (FPB) is typically used to modify metal surfaces
    by bombarding them with fine particles at high speed. FPB is not a coating technique
    but is used for forming microscale concavities and convexities on a surface. Previously,
    we reported that an FPB-treated surface showed antibacterial effects; however,
    the underlying mechanisms remain unclear. We hypothesized that the pitch size
    of concavity and convexity, and irregular microscale pattern of FPB-treated surfaces
    might contribute to the antibacterial performance. In this study, we applied FPB
    to stainless-steel surfaces and evaluated the antibacterial effects of the FPB-treated
    surfaces based on ISO 22,196:2007. The FPB-treated surfaces exhibited antibacterial
    activity against Escherichia coli, with an antibacterial activity value (R) of
    two or more. Furthermore, our experiments suggest that the antibacterial mechanism
    of the FPB-treated surface can be attributed to increased oxidative stress in
    bacteria owing to physical stress from the rough surface. The antibacterial effect
    of FPB-treated surfaces offers an effective measure against drug-resistant bacteria.
