Fluorescence microscopy is a powerful imaging technique used to visualize biological samples. It works by illuminating the sample with specific wavelengths of light, causing certain molecules, known as fluorophores, to emit light at different wavelengths. This emitted light is then captured to create detailed images, allowing scientists to study the structure and function of cells and tissues. This method is particularly useful in cell biology and medical research, as it can highlight specific proteins or other cellular components tagged with fluorescent dyes. By using multiple dyes, researchers can observe various elements within a single sample, providing insights into complex biological processes.
