Fluorescent probes are small molecules or proteins that can emit fluorescence when they bind to specific targets or molecules of interest within a biological system. These probes are widely used in various research areas, such as cell biology, biochemistry, and molecular biology, to visualize and track the localization, dynamics, and interactions of biomolecules in living cells and tissues. Fluorescent probes are valuable tools for studying biological processes, detecting disease markers, and monitoring cellular responses to stimuli. They can be designed to target specific cellular structures, proteins, nucleic acids, or small molecules, allowing researchers to visualize and study them in real time with high sensitivity and resolution. The development of novel fluorescent probes continues to be a growing field in research, with advancements in probe design, synthesis, and applications driving discoveries in various areas of biomedical and life sciences.
