In this paper, we report on the development of a filter-free fluorescence sensor for the detection of multiple fluorescence wavelengths from a solution of fluorescent dyes with submicromolar concentrations. The filter-free fluorescence sensor has a photo-gate structure, and the intensities of excitation light and fluorescence can be calculated from the photocurrents for the different gate voltages...
We proposed a cell analysis system without optical filters using a filter-free fluorescence sensor which used wavelength dependent absorption depth in a silicon substrate. Excitation light and fluorescence from fluorescently labeled cells were separated and their light intensities were measured at the same time by applying the proposed parameter. This result shows the filter-free fluorescence sensor...
In this paper, the detection of fluorescence from the solution of a fluorescent dye with a submicromolar concentration by the filter-free fluorescence sensor is reported. The filter-free fluorescence sensor has a photo-gate structure and the intensities of excitation and fluorescent lights can be calculated from the photocurrents for different gate voltages. It makes it possible to measure various...
