Study by fluorescence of calix[4]arenes bearing heterocycles with divalent metals: highly selective detection of Pb2+
(Springer, 2014)
The present work describes a study of complexation
efficiency and selectivity of calix[4]arenes bearing
benzoimidazolyl, benzothiazolyl, and benzoxazolyl heterocycles
(5–7) towards several selected metal ions ...
The development of a fluorescence turn-on sensor for cysteine, glutathione and other biothiols. A kinetic study
(Elsevier, 2011)
Two fluorescence probes for the detection of cysteine (Cys), glutathione (GSH) and other biothiols, such as homocysteine (Hcy) and cysteinyl-glycine (Cys-Gly), were developed. These molecular probes are coumarin-based ...
Comparative steady-state fluorescence studies of cytosolic rat liver (GTP), Saccharomyces cerevisiae (ATP) and Escherichia coli (ATP) phosphoenolpyruvate carboxykinases
(1993)
Two members of the ATP-dependent class of phosphoenolpyruvate (PEP) carboxykinases (Saccharomyces cerevisiae and Escherichia coli PEP carboxykinase), and one member of the GTP-dependent class (the cytosolic rat liver enzyme) ...
Blue-Fluorescent Probes for Lipid Droplets Based on Dihydrochromeno-Fused Pyrazolo- and Pyrrolopyridines
(Wiley-VCH Verlag, 2018)
© 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Lipid droplets (LDs) have been recognized as highly dynamic cellular organelles involved in important biological functions for the survival of organisms such as supplying ...
Design and synthesis of a new coumarin-based 'turn-on' fluorescent probe selective for Cu +2
(2012)
The novel coumarin-based 'turn-on' fluorescent probe (E)-3-(2,5- dimethoxybenzylideneamino)-7-hydroxy-2H-chromen-2-one (MGM) was designed, synthesized, and characterized. This compound shows high selectivity for Cu +2, ...
Fluorescence and surface-enhanced vibrational spectroscopies of lawsone and plumbagin
(Taylor and Francis Inc., 2016)
© 2016, Copyright © Taylor & Francis Group, LLC. The natural dyes lawsone and plumbagin (1,4-naphthoquinones) were studied by using fluorescence, Raman, infrared (IR), surface-enhanced Raman scattering (SERS), and ...
A selective fluorescent probe for the detection of mercury (II) in aqueous media and its applications in living cells
(2012)
In this Letter we present a new probe, 2-amino-3-hydroxy-2-(hydroxymethyl) propyl 2-(7-hydroxy-2-oxo-2H-chromen-4-yl)acetate (PMR), which can reversibly detect mercuric ions (Hg 2+) in HEPES buffer under physiological ...
Deltamethrin determination in natural water samples via photochemically-induced fluorescence coupled to third-order multivariate calibration
(Elsevier, 2020)
In this work, an analytical method for deltamethrin determination in natural waters based on photochemicallyinduced fluorescence coupled to third-order/four-way calibration was evaluated and compared with secondorder/three-way ...
Determination of imidacloprid in water samples via photochemically induced fluorescence and second-order multivariate calibration
(Elsevier, 2015)
This paper presents a new method for the determination of imidacloprid in water samples; one of the most widely used neonicotinoid pesticides in the farming industry. The method is based on the measurement of excitation-emission ...
