Outline of Final Research Achievements |
We tried to pioneer the principle of "Optical Guiding Bacteria Trap Method" for the optical control of bacterial uptake into polymer film. And, we conducted research to develop disinfection method of malignant bacteria, and to produce functional polymer films with densely trapped useful bacteria. The main results are described below: (1) By accumulating bacteria on a flat light absorbing thin film by laser irradiation, the number of bacteria in the liquid can be measured within several minutes, and the conditions for killing the malignant bacteria were also clarified. (2) By clarifying the conditions for the optical guiding of bacteria into honeycomb-shaped micropores with high survival rate (90% or more), we applied them to electrical current generating bacteria. Remarkably, we have clarified that the maximum current value can be obtained 3 to 4 times faster than conventional methods, and revealed the applicability to electrochemical devices.
