Fluorescent microscopy is a powerful imaging technique used to visualize specific components within cells and tissues. It works by using high-intensity light to excite fluorescent dyes or proteins that are attached to the target molecules. When these molecules absorb light, they emit light at a longer wavelength, allowing researchers to see them against a darker background. This method is widely used in biological research and medical diagnostics because it provides detailed images of cellular structures and processes. By using different fluorescent markers, scientists can study multiple targets simultaneously, enhancing our understanding of complex biological systems.
