Examples

• The nonfluorescent dye did not glow under ultraviolet light.
• Most minerals are nonfluorescent and do not emit visible light when exposed to radiation.
• The laboratory used nonfluorescent markers to avoid interference with the fluorescence microscopy experiment.
• Unlike fluorescent proteins, nonfluorescent variants are invisible under standard imaging conditions.
• The nonfluorescent coating on the surface made it difficult to detect with optical methods.
