  • Patent number: 12117387
    Abstract: The present invention provides a cell measurement device and method in which retroreflective particles are introduced to measure cells, and thus, an optical signal is obtained without fixing of life activity of cells and performing a separate staining process. An example of the use of retroreflection-based cytometry is evaluation of cell migration. The cells capture the retroreflective particles during cell migration or growth, and migrate in a state that the particles are captured in the cell or bind to the cells. The migrated cells are observed in a form of bright dots inside the cells under irradiation of white light as a non-spectroscopic light source to the cells in the retroreflective optical system. The number of bright spots is counted, and thus, the number of cells and the presence thereof thus can be easily measured based on an image.
