| Outline of Final Research Achievements |
Recently, the technique to impart biocompatibility and also clean biomaterials is required. In this study, we investigated physical cleaning metallic materials and imparted photocatalytic function. We used wet blast technique as physical cleaning for the specimen of stainless steel (SUS316L). The projection particles were nanoparticles of titanium dioxide (TiO2). It was possible to impart photocatalytic function to the processed surface by controlling the air pressure (Pair), slurry pressure (Pslu) and processing time. It was possible to remove biofilms of Bacillus natto and also impart photocatalytic function on the surface after cleaning. We found that the cleaning method using the wet blast technique for metallic materials has a possibility of physical cleaning and the photocatalytic function imparting.
