Fluorescent microscopy is a powerful imaging technique used to visualize specific components within cells and tissues. It works by using a light source 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 and medical research, enabling scientists to study cellular processes, protein interactions, and disease mechanisms. Fluorescent microscopy can be combined with other techniques, such as confocal microscopy, to enhance image resolution and provide three-dimensional views of samples.
