Fluorescence probes are molecules that exhibit fluorescence when exposed to light of a specific wavelength. These probes are commonly used in bioimaging and diagnostic applications to visualize and track biomolecules, cells, and tissues. They can also be used to monitor various biological processes and interactions in real time. Fluorescence probes are versatile tools in research, providing valuable insights into the structure, function, and dynamics of biological systems. They are designed with specific properties such as excitation and emission wavelengths, brightness, photostability, and targeting capabilities to suit their intended application. Overall, fluorescence probes play a crucial role in advancing our understanding of biological mechanisms and diseases.
