Fluorescent imaging is a technique used in biological and medical research to visualize and study specific molecules or structures within cells or tissues. This imaging method relies on the use of fluorescent tags or dyes that emit light when exposed to a specific wavelength of light. By labeling molecules or structures of interest with fluorescent markers, researchers can track their movement and localization in real-time, allowing for a better understanding of cellular processes and interactions. Fluorescent imaging is commonly used in various fields such as cell biology, neuroscience, and immunology to study protein localization, gene expression, cell signaling, and more.
