Epi-fluorescence

Epi-fluorescence is a microscopy technique that uses fluorescent light to visualize samples, such as cells or tissues. In this method, a fluorescent dye is applied to the sample, which absorbs specific wavelengths of light and then emits light at a different wavelength. The microscope captures this emitted light from above the sample, allowing researchers to see structures or specific molecules clearly and in color. This technique is valuable in biology and medicine for studying the detailed features of cells, tracking proteins, and observing interactions within living organisms.
