The detection limit is determined by the ability to distinguish each fluorescentmolecule from the background. When the fluorescentmolecule is brought to the excited state it relaxes back emitting the very same fluorescence as in the one-photon excitation case. However, collecting more photons from an organic fluorescentmolecule and reducing background is challenging. Generally, fluorescent tagging, or labeling, uses a reactive derivative of a fluorescentmolecule known as a fluorophore.

Because of the sensitivity that the method affords, fluorescentmolecule concentrations as low as 1 part per trillion can be measured.

Therefore, anisotropy measurements can be used to investigate how freely a fluorescentmolecule moves in a particular environment.

Modern fluorometers are capable of detecting fluorescentmolecule concentrations as low as 1 part per trillion.

It has been found, however, that the chemiluminescence intensity corrected for quantum yield decreases as the singlet excitation energy of the fluorescentmolecule increases 6.

Because each fluorescentmolecule has a unique spectrum of absorption and emission, the location of particular types of molecules can be determined.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Azo-initiators are considered to produce the peroxyl radical by heating, which damages the fluorescentmolecule, resulting in the loss of fluorescence. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. One of the major limitations in this direction is the difficulty of predicting or measuring two-photon absorption spectra of the fluorescent molecules used. These methods measure the distance between two identical fluorescent molecules. The other is using multiply labeled fluorescent molecules. An oxygenscavenging system stabilizes organic fluorescent molecules, allowing them to produce more photons and increases the possible observation time. The resolution is now the distance between the fluorescent molecules. However, photobleaching may also be used prior to applying the (primarily antibody-linked) fluorescent molecules, in an attempt to quench autofluorescence.

However, the actual dye concentration can be low to minimize the disturbance of biological systems: some instruments can track single fluorescent molecules.
