| Outline of Final Research Achievements |
In a traditional photoacoustic flow cytometry, cells in vessels are aligned in one line by laser manipulation, and the photoacoustic signals induced from the cells are measured to classify the characteristics. However, scattering and absorption in the living tissues has effects on the propagation of the radiated laser, and the alignment of the cell by the manipulation cannot be achieved owing to the effect. In this study, the effect of the scattering and absorption was minimized by acoustical focusing, and the method could visualize the living tissues at the deeper part was developed.
