FAQ
Frequently Asked Questions
Not exactly. While all fluorophores are dyes, not all dyes are fluorophores. A fluorophore specifically fluoresces (emits light upon excitation), whereas a dye may simply colour a substance without fluorescence.
Yes, many fluorophores are designed to be biocompatible and are used for live-cell imaging and in vivo studies in animals.
Excitation is the specific wavelength of light the fluorophore absorbs. Emission is the longer (lower energy) wavelength of light it subsequently releases, which is what we detect and see.
In standard laboratory use with proper safety equipment (e.g., gloves, eye protection), they are generally safe. However, specific compounds may have individual hazards, so their Safety Data Sheets (SDS) must always be consulted.

Mnemonic
Think: FLUORophore = FLUOrescent + PHORE (bearer). It's a 'bearer of fluorescence'.
Conceptual Metaphor
A tiny, man-made firefly attached to a molecule to make it glow and reveal its location.
