Fluorescent imaging is a technique used to visualize and study biological samples by detecting the fluorescence emitted from specific molecules. This method involves labeling target molecules with fluorescent dyes or proteins, which emit light when exposed to certain wavelengths. Researchers can then capture images of these samples using specialized cameras and microscopes, allowing for detailed observation of cellular structures and processes. This imaging technique is widely used in fields such as cell biology, molecular biology, and medical diagnostics. It helps scientists understand complex biological interactions, track the movement of proteins, and identify disease markers, contributing to advancements in research and healthcare.
