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 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 ...

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.

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 ...

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 ...
