Fluorescence and autofluorescence

Best Practice & Research Clinical Gastroenterology, 1999
Fluorescence 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.

On the autofluorescence of fingermarks

Forensic Science International, 2012
The autofluorescence of fingermarks is used for their detection. The components responsible for this autofluorescence are largely unknown. Thin layer chromatography and fluorescence spectroscopy were used to identify autofluorescent components and evaluate their forensic value.

Autofluorescent Proteins

2008
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.

Laser Applications and Autofluorescence

2020
The diagnostic pathway for oral suspicious lesions usually starts with the clinical examination based on inspection and palpation of the oral mucosa. Such a phase is strongly related to the experience of the operator. Moreover, oral epithelial dysplasia and early oral carcinomas may already be present within areas of macroscopically intact oral mucosa.

On the autofluorescence of aged fingermarks

Forensic Science International, 2016
Fingermark autofluorescence changes with time, both spectrally and in total intensity. In this study we investigate which components in the aged fingermarks cause this change in autofluorescent signal. Thin layer chromatography combined with fluorescence spectroscopy was used to identify fluorescent aging products.

Fundus Autofluorescence

2018
Fundus autofluorescence (FAF) imaging is a rapid and noninvasive technique to evaluate retinal pigment epithelial (RPE) function. The predominant source of FAF in the macula is lipofuscin granules.

Autofluorescence of intraocular tumours

Current Opinion in Ophthalmology, 2013
Fundus autofluorescence is a noninvasive technique for evaluation of intrinsic autofluorescence of the tissues within the eye. In recent years, autofluorescence has become an important diagnostic tool for the assessment of various ocular diseases such as age-related macular degeneration and retinal dystrophies.
