WebOne of the most common way to determine interactions at the molecular scale in cells is to measure fluorescence (or Förster) resonance energy transfer (FRET) [21, 22]. Such a transfer occurs between two fluorophores, when one of them called the donor transfers its energy to another fluorophore, called the acceptor, without photon emission [23]. WebIn biological sciences, the fluorophore can be conjugated to such proteins as antibodies for antigen detection etc given that it is capable of emitting bright fluorescence. …
