fluorescent dyes

Fluorescent dyes are chromophores (light-absorbing molecules) that absorb photons at a specific excitation wavelength and re-emit them at a longer emission wavelength, enabling the visualization of biological structures. Widely used in microscopy, flow cytometry, and molecular biology, these dyes help label and track cells, proteins, and other molecules in complex systems. Their ability to provide high-contrast imaging makes them essential in both research and diagnostic applications.
