Influence of dental materials used for sealing caries lesions on laser fluorescence measurements
(SPRINGER LONDON LTDLONDON, 2012)
The aim of this study was to determine the influence of thickness and aging on the intrinsic fluorescence of sealing materials and their ability to block fluorescence from the underlying surface as assessed using a laser ...
Revealing a new fluorescence peak of the enhanced green fluorescent protein using three-dimensional fluorescence spectroscopy
(Royal Soc Chemistry, 2019-08-01)
Fluorescent proteins have many applications as biomarkers and biosensors in the medical and biological fields. Their success was largely supported by modifications of the first isolated fluorescent protein, the wild-type ...
Fluorescent probes with malononitrile side group in methyl methacrylate copolymers
(ELSEVIER SCIENCE SA, 2008)
Fluorescent probes derivated from auramine, 1-aminopyrene, and 9-aminoacridine containing a malononitrile group are copolymerized with methyl methacrylate. These new fluorescent polymeric materials are studied in solution ...
Reversible and irreversible fluorescence activity of the Enhanced Green Fluorescent Protein in pH: Insights for the development of pH-biosensors
(2020-12-01)
Enhanced Green Fluorescent Protein (EGFP) is a biomolecule with intense and natural fluorescence, with biological and medical applications. Although widely used as a biomarker in research, its application as a biosensor ...
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 ...
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, ...
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 ...
