Fluorescence Correlation Spectroscopy [PDF]

, 2011
Fluorescence correlation spectroscopy (FCS), implemented in microscopy, relies on performing an autocorrelation of the time fluctuating intensity arising from individual molecules diffusing through a confocal volume. It allows us to investigate a large variety of dynamic processes and to quantify photophysical, photochemical, interaction, diffusion ...

Investigation of Leaf Diseases and Estimation of Chlorophyll Concentration in Seven Barley Varieties Using Fluorescence and Hyperspectral Indices

Remote Sensing, 2013
Leaf diseases, such as powdery mildew and leaf rust, frequently infect barley plants and severely affect the economic value of malting barley. Early detection of barley diseases would facilitate the timely application of fungicides. In a field experiment,

Fluorescence Corralation Spectroscopy [PDF]

Biophysical Journal, 2005
Identifying submicroscopic corrals in the plasma membrane has been of interest since the classic Sheetz barnyard model of confinement of proteins by the erythrocyte membrane skeleton (1). In this issue, Wawrezinieck et al. (2) present a novel fluorescence correlation spectroscopy (FCS) method to identify corrals.

BILIPROTEINS FROM THE BUTTERFLY Pieris brassicae STUDIED BY TIME-RESOLVED FLUORESCENCE AND COHERENT ANTI-STOKES RAMAN SPECTROSCOPY [PDF]

, 1988
The fluorescence decay time of the biliverdin IX7 chromophore present in biliproteins isolated from Pieris brassicae is determined to be 44 ± 3 ps. This value suggests a cyclic helical chromophore structure. The vibrational frequencies determined by CARS-

Time-resolved FRET fluorescence spectroscopy of visible fluorescent protein pairs

, 2010
Förster resonance energy transfer (FRET) is a powerful method for obtaining information about small-scale lengths between biomacromolecules. Visible fluorescent proteins (VFPs) are widely used as spectrally different FRET pairs, where one VFP acts as a ...
