Fluorescence correlation spectroscopy

BioEssays, 2012
AbstractFluorescence correlation spectroscopy (FCS) is a powerful technique to measure concentrations, mobilities, and interactions of fluorescent biomolecules. It can be applied to various biological systems such as simple homogeneous solutions, cells, artificial, or cellular membranes and whole organisms. Here, we introduce the basic principle of FCS,

Fluorescence and Raman Spectroscopy

Gastrointestinal Endoscopy Clinics of North America, 2009
Reflectance spectroscopy is an emerging technology which provides rapid and safe evaluation of tissue for dysplasia and ischemia. The probe-based devices can be passed through most endoscopes. Current applications include detection of dysplasia in Barrett's esophagus, colitis, and colon polyps.

Fluorescence and Raman spectroscopy

Gastrointestinal Endoscopy Clinics of North America, 2003
Table 2 provides a summary of selected in vivo fluorescence and Raman studies performed in BE. Although the findings from these studies appear promising, these techniques are still under development, and it is anticipated that technological refinements will further enhance their diagnostic accuracy. Ultimately, however, large-scale prospective clinical

Fluorescence Spectroscopy

2003
This chapter has introduced the theory of fluorescence, and briefly shown that it is a technique with many wide and varied applications in biochemistry. It has the overall advantage of being able to carry out measurements on small amounts of sample in solution, often revealing important information concerning the structure and dynamics of these systems.

Fluorescence Spectroscopy of Peptides

2013
In peptides, steady-state fluorescence can be used to measure the intrinsic fluorescence of Trp, Tyr, and Phe residues, as well as associated dyes, which can change upon exposure to different environmental conditions. This technique can be thus used to detect changes in the conformational states of peptides.

Fluorescence Correlation Spectroscopy

2007
Fluorescence correlation spectroscopy (FCS) is a technique that allows for an extremely sensitive determination of molecular diffusion properties, down to the level of single molecules. It thus provides an attractive alternative to FRAP, requiring much less laser power and lower concentrations of fluorophores.
