FRET
Fluorescence Resonance Energy Transfer, also known as Foerster Resonance Energy Transfer (FRET in both cases) is the term given to the process where two excited "fluorophores" pass energy one to the other non-radiatively (i.e., without exchanging a photon). By carefully selecting the excitation of these flurophores and detecting the emission, FRET has become one of the most widely used techniques in the field of Biophotonics, giving scientists the chance to investigate sub-cellular environments.

Famous quotes containing the word fret:
“O Master, let me walk with thee
In lowly paths of service free;
Tell me thy secret; help me bear
The strain of toil, the fret of care;”
—Washington Gladden (1836–1918)
“Heaven has its business and earth has its business: those are two separate things. Heaven, that’s the angels’ pasture; they are happy; they don’t have to fret about food and drink. And you can be sure that they have black angels to do the heavy work like laundering the clouds or sweeping the rain and cleaning the sun after a storm, while the white angels sing like nightingales all day long or blow in those little trumpets like they show in the pictures we see in church.”
—Jacques Roumain (1907–1945)
“Cassius. Must I endure all this?
Brutus. All this? Ay, more! Fret till your proud heart break.”
—William Shakespeare (1564–1616)
