👉 The Rhode fluid, also known as rhodamine, is a synthetic fluorescent dye first synthesized in 1888 by French chemist Louis Rhône. It is widely used in various scientific applications, particularly in biological and medical research, due to its bright green fluorescence under ultraviolet (UV) light. When excited by UV light, Rhode fluid emits light at a longer wavelength, making it highly useful for labeling and tracking molecules in cells and tissues. This property facilitates the visualization of cellular processes, protein interactions, and other biological phenomena under microscopy, providing researchers with a powerful tool for understanding complex biological systems.
