Photoluminescence and Fluorescence Quenching of Graphene Oxide: A Review

open access: yesNanomaterials, 2022
In recent decades, photoluminescence (PL) material with excellent optical properties has been a hot topic. Graphene oxide (GO) is an excellent candidate for PL material because of its unique optical properties, compared to pure graphene. The existence of

From 2,3-Diazabicyclo[2.2.2]oct-2-ene to Fluorazophore-L, a membrane-bound fluorescent probe for antioxidants [PDF]

open access: yes, 2004
The aim of this work was to synthesize and to establish a new fluorescent membrane probe for antioxidants by exploiting the exceptional properties of the long-lived fluorophore 2,3-diazabicyclo[2.2.2]oct-2-ene (DBO) alias Fluorazophore-P.

Fluorescence of Alexa fluor dye tracks protein folding. [PDF]

open access: yesPLoS ONE, 2012
Fluorescence spectroscopy is an important tool for the characterization of protein folding. Often, a protein is labeled with appropriate fluorescent donor and acceptor probes and folding-induced changes in Förster Resonance Energy Transfer (FRET) are ...

Low-temperature quenching of one-dimensional localised Frenkel excitons [PDF]

open access: yes, 2003
We present a theoretical analysis of low-temperature quenching of one-dimensional Frenkel excitons that are localised by moderate on-site (diagonal) uncorrelated disorder.

Fullerenol Quantum Dots-Based Highly Sensitive Fluorescence Aptasensor for Patulin in Apple Juice

open access: yesToxins, 2022
A highly selective and sensitive aptasensor for detecting patulin (PAT) was constructed based on the fluorescence quenching of fullerenol quantum dots (FOQDs) towards carboxytetramethylrhodamine (TAMRA) through PET mechanism. The π-π stacking interaction

Quenching of the fluorescence of NO2 [PDF]

open access: yesJournal of Photochemistry, 1972
The fluorescence yield of NO2 was monitored at 25 C with incident wavelengths of 4047, 4358, and 4800A at fluorescence wavelengths of 4860, 5577, and 6300A. The NO2 pressure was varied between 0.004 and 0.080 torr. Measurements were taken both in the absence of foreign gases and in the presence of up to 30 torr. He, N2, and O2 at each NO2 pressure.

Reaction Mechanism Spectroscopy Studies of Protein and Orange II

open access: yesChemical Engineering Transactions, 2015
In this paper, the interaction of Orange II and Human Serum Albumin was studied by fluorescence spectroscopy under simulated physiological conditions. The affection of pigment and serum albumin may cause changes in the microenvironment.
