FLUORESCENCE AND FLUORESCENCE CONVERSION [PDF]

open access: possible, 1965
Abstract : The quenching constant for the iodide quenching of the fluorescence of riboflavin phosphate was measured at pH 5 and at pH 8. The value of this constant (K1) at the lower pH (where the phosphate group is unionized), was independent of the ionic strength, mu.

A Fluorescence and Fluorescence Probe Study of Benzonaphthyridines

Journal of Fluorescence, 2011
A series of benzo[b][1,8]naphthyridines has been synthesized by Friedländer condensation of 2-aminoquinoline-3-carbaldehyde 1 (o-aminoaldehyde) with alicyclic ketones in basic medium. Benzonaphthyridines branched with various side-chains and substituents are prepared with the aim of being investigated as a good fluorescent material.

Fluorescence spectroscopy of tissue: recovery of intrinsic fluorescence from measured fluorescence

Applied Optics, 1996
We present a method for recovering the intrinsic fluorescence coefficient, defined as the product of the fluorophore absorption coefficient and the fluorescence energy yield, of an optically thick, homogeneous, turbid medium from a surface measurement of fluorescence and from knowledge of medium optical properties.

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 ...

Fluorescence Microscopy

2019
In this two-part chapter, the background to confocal microscopy and two-photon fluorescence microscopy is first presented, with a detailed description of the optical setup. This is followed by a critical account of the many super-resolution techniques: coordinated stochastic fluorescence microscopy (photoactivation localization microscopy ...

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.

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 ...
