Fluorescent markers

Fluorescent markers are special chemicals used in biological research that emit light when exposed to certain wavelengths, typically UV or blue light. They are attached to molecules like DNA, proteins, or cells, allowing scientists to visually track and identify specific structures or processes under a microscope. When illuminated, the markers glow brightly, making it easier to study how cells work, how diseases develop, or how treatments impact biological systems. This technique enhances observation precision without damaging the sample, providing valuable insights in areas like medicine, genetics, and microbiology.
