| Outline of Final Research Achievements |
The purpose of this study is to obtain knowledge about the materials on which the adhesion of microorganisms and biofilms is limited, revealed by AFM observation on the behavior of adhesion volume and shape of microorganisms and biofilms on various materials. It has been found that the adhesion volume and shape of microorganisms and biofilms are strongly dependent on the materials revealed by AFM observation. Adhesion work of the water containing some of the components of biofilms, such as alginate or rhamnolipid, on various materials has been also investigated, and the relationship between the adhesion work and the adhesion volume and shape of biofilms has been discussed.
