Fluorescence or Forster resonance energy transfer (FRET) is widely accepted as being one of the most useful methods to observe biochemical events in vitro and in living cells. Generally, there are two forms of FRET sensors those based on a pair of genetically encoded fluorophores, usually employing fluorescent proteins from jellyfish or corals, or those based on small molecules that make use of small organic fluorophores.
