Fluorescence Resonance Energy Transfer

Fluorescence Resonance Energy Transfer (FRET) is a special technique to gauge the distance between two chromophores, called a donor-acceptor pair. The limitation of FRET is that this transfer process is effective only when the separating distance of donor-acceptor pair is smaller than 10 nanometers. However, FRET is a highly distance-dependent

Basic Principles of Fluorescence and Energy Transfer

Since fluorescence intensity is the most commonly and easily measured fluorescence property, measurement of fluorescence lifetimes and fluorescence polarization will not be discussed. Only the most basic elements of fluorescence can be provided in a single chapter, and full texts on the subject should be consulted for greater detail ( 1, 2 ).
