Fundamentals of Fluorescence and Fluorescence Microscopy

2003
This chapter discusses the fundamental physics of fluorescence. The application of fluorescence to microscopy represents an important transition in the development of microscopy, particularly as it applies to biology. It enables quantitating the amounts of specific molecules within a cell, determining whether molecules are complexing on a molecular ...

Enhancement and quenching of single-molecule fluorescence.

Physical Review Letters, 2006
We present an experimental and theoretical study of the fluorescence rate of a single molecule as a function of its distance to a laser-irradiated gold nanoparticle.

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.

Molecular Fluorescence in Citric Acid-Based Carbon Dots

, 2017
Nitrogen-doped carbon dots synthesized from citric acid as a carbon precursor have recently been considered to contain fluorescent derivatives of citrazinic acid, which contribute to their emission in the blue spectral range.

Fluorescence Microscopy

Current Protocols in Immunology, 1998
AbstractAbsorption of energy as light by some molecules and emission of energy as fluorescence can occur only at certain wavelengths, which are characteristic for a given molecule (fluorophore). Fluorescence microscopes are equipped to observe the fluorescence of one or more specific fluorophores to localize specific molecules and analyzed cellular ...

Fluorescent proteins for single‐molecule fluorescence applications

Journal of Biophotonics, 2008
AbstractWe present single‐molecule fluorescence data of fluorescent proteins GFP, YFP, DsRed, and mCherry, a new derivative of DsRed. Ensemble and single‐molecule fluorescence experiments proved mCherry as an ideally suited fluorophore for single‐molecule applications, demonstrated by high photostability and rare fluorescence‐intensity fluctuations ...

Environmental effects on vibronic band intensities in pyrene monomer fluorescence and their application in studies of micellar systems

, 1977
The fluorescence intensities for various vibronic fine structures in the pyrene monomer fluorescence show strong solvent dependence. In the presence of polar solvents, there is a significant enhancement in the intensity of the 0--0 vibronic band at the ...
