Fluorescence Correlation Spectroscopy [PDF]

open access: yes, 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 ...

Exploratory analysis of excitation-emission matrix fluorescence spectra with self-organizing maps as a basis for determination of organic matter removal efficiency at water treatment works [PDF]

open access: yes, 2009
In the paper, the self-organizing map (SOM) was employed for the exploratory analysis of fluorescence excitation-emission data characterizing organic matter removal efficiency at 16 water treatment works in the UK.

A superior bright NIR luminescent nanoparticle preparation and indicating calcium signaling detection in cells and small animals

open access: yesCell & Bioscience, 2018
Background Near-field fluorescence (NFF) effects were employed to develop a novel near-infrared (NIR) luminescent nanoparticle (LNP) with superior brightness. The LNP is used as imaging contrast agent for cellular and small animal imaging and furthermore

Nanosecond Fluorescence Spectroscopy [PDF]

open access: yesIEEE Transactions on Nuclear Science, 1985
This article is a summary of a short course lecture given in conjunction with the 1984 Nuclear Science Symposium. Measuring systems for nanosecond fluorescence spectroscopy using single-photon counting techniques are presented. These involve systems based on relaxation-type spark gap light pulser and synchronously pumped mode-locked dye lasers ...

Tracking-FCS: Fluorescence correlation spectroscopy of individual particles [PDF]

open access: yes, 2005
We exploit recent advances in single-particle tracking to perform fluorescence correlation spectroscopy on individual fluorescent particles, in contrast to traditional methods that build up statistics over a sequence of many measurements.

Fluorescence Corralation Spectroscopy [PDF]

open access: yesBiophysical 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.

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

open access: yesRemote 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,

Characterization and digital restauration of XIV-XV centuries written parchments by means of non-destructive techniques. Three case studies [PDF]

open access: yes, 2018
Parchment is the primary writing medium of the majority of documents with cultural importance. Unfortunately, this material suffers of several mechanisms of degradation that affect its chemical-physical structure and the readability of text.
