Fluorescence and autofluorescence
Best Practice & Research Clinical Gastroenterology, 1999Fluorescence detection is one of a series of new spectroscopic techniques currently developed for implementation in endoscopy. This technology is likely to significantly enhance our ability to detect minute lesions and to predict the histology of certain macroscopic lesions.

Autofluorescent proteins (AFPs) have revolutionized molecular cell biology, and applications continue to harness the power of these genetically encoded fluorescent tags. Here, we review the discovery and physical properties of AFPs as well as their development through mutational optimization for several functional parameters.

Optometry and Vision Science, 2012
Recent technological advances in fundus autofluorescence (FAF) are providing new opportunities for insight into retinal physiology and pathophysiology. FAF provides distinctly different imaging information than standard photography or color separation. A review of the basis for this imaging technology is included to help the clinician understand how to

Gastrointestinal Endoscopy Clinics of North America, 2009
Autofluorescence endoscopy is a wide area imaging technique, with the ability to rapidly examine a large surface area of gastrointestinal mucosa to detect small areas of dysplasia or cancer. It has potential in diseases such as Barrett's esophagus, ulcerative colitis, and gastric cancer, in which large areas of mucosa may harbor areas of dysplasia or ...

Diagnostic Techniques: Autofluorescence
2013Autofluorescence is a relatively new, noninvasive diagnostic tool recently introduced in the armamentarium of intraocular tumor diagnosis and characterization. This technique may reveal the effects of choroidal tumors on the overlying retinal pigment epithelium and may also provide specific information on intrinsic pigments that compose and ...

AUTOFLUORESCENCE OF CHOROIDAL MELANOMAS
RETINAL Cases & Brief Reports, 2007To report autofluorescence findings for two patients with choroidal melanomas.Records and photographs for two patients with choroidal melanomas were reviewed. Fundus autofluorescence photography was performed using the Heidelberg confocal SLO system (Heidelberg Retina Angiograph; Heidelberg Engineering, Dossenheim, Germany).Both patients had lipofuscin

The autofluorescence of cell walls or cell wall parts can be quantified by microspectroscopy. In lignified cell walls it is mainly phenol rings which give rise to autofluorescence. The intensity of autofluorescence depends on the cell wall composition and construction.
