1. a group of synthetic red or pink fluorescent dyes used in biological research, laser technology, and as tracers
Usage: technical; chemistry

Examples

• The researchers used rhodamines to stain the cell membranes for microscopic observation.
• Rhodamines are commonly employed as fluorescent markers in molecular biology experiments.
• The laser dye contained rhodamines to produce intense red light.
• Scientists added rhodamines to the water to trace the flow patterns in the river.
• The fluorescence microscope detected the rhodamines bound to the protein structures.
• Rhodamines exhibit strong absorption and emission properties in the visible spectrum.
