Keywords:filter-free, fluorescence sensor

We proposed a cell analysis system without optical filters using a filter-free fluorescence sensor which used wavelength dependent absorption depth in a Si substrate. Excitation light and fluorescence from fluorescently labeled cells were separated and the light intensities were measured at the same time by applying the proposed parameter. This result shows the filter-free fluorescence sensor can be used to detect labeled cells with various fluorescence reagents. The measured fluorescence of cells was good agreement with fluorescence intensity observed by conventional fluorescence microscopy.
