Study of SnO2 gels by Eu3+ fluorescence spectroscopy
(1992-12-01)
Eu3+ fluorescence spectroscopy was used as a probe to study the changes in local arrangements of tin oxyhydroxide precipitate → sol → gel → glass conversion. Electronic transition intensities and 5D0 excited state lifetime ...

A Smartphone-Based Low-Cost Inverted Laser Fluorescence Microscope for Disease Diagnosis
(MDPI, 2022)
Fluorescence microscopy is an important tool for disease diagnosis, often requiring costly optical components, such as fluorescence filter cubes and high-power light sources. Due to its high cost, conventional fluorescence ...
Effect of different artificial aging protocol-son fluorescence of resin composites
(2018-01-01)
This study evaluated the effect of different artificial aging on fluorescence of resin composites. Forty-five cylindrical specimens (6mm in diameter and 1mm thick) were made of each resin composite: IPS Empress Direct, ...
Fluorescent fingerprints of edible oils and biodiesel by means total synchronous fluorescence and Tucker3 modeling
(Pergamon-Elsevier Science Ltd, 2017-03)
The present work proposes the use of total synchronous fluorescence spectroscopy (TSFS) as a discrimination methodology for fluorescent compounds in edible oils, which are preserved after the transesterification processes ...
Microneedles rollers as a potential device to increase ALA diffusion and PpIX production: evaluations by wide-field fluorescence imaging and fluorescence spectroscopy
(International Society for Optical Engineering - SPIEBellingham, 2014)
One of the limitations of topical photodynamic therapy (PDT) using 5-aminolevulinic acid (ALA) is the poor ability to penetrate biological barriers of skin and the recurrence rates in treatments. This study aimed to identify ...

Interaction of a synthetic antimicrobial peptide with model membrane by fluorescence spectroscopy
(Springer, 2013-12-01)
Static and time-resolved fluorescence of tryptophan and ortho-aminobenzoic acid was used to investigate the interaction of the synthetic antimicrobial peptide L1A (IDGLKAIWKKVADLLKNT-NH2) with POPC and POPC:POPG. N-acetylated ...
