Detection of subcellular nitric oxide in mitochondria using a pyrylium probe: assays in cell cultures and peripheral blood
Royal Society of Chemistry (2021-11-25)Fluorescent probes for the detection of intracellular nitric oxide (NO) are abundant, but those targeted to the mitochondria are scarce. Among those molecules targeting mitochondrial NO (mNO), the majority use a ... -
Localized intracellular pH measurement using a ratiometric photoinduced electron-transfer-based nanosensor
Wiley (2012-09)Intracellular analysis: Changes in the concentration of hydrogen ions can lead to cellular dysfunction. Thus, quantification of the intracellular pH in localized compartments (see A and B) is important. A pH nanosensor ... -
Photobehavior of the antipsychotic drug cyamemazine in a supramolecular gel protective environment
Elsevier (2019-11-06)In this work, a molecular hydrogel made of gelator (S)-4-((3-methyl-1-(nonylamino)-1-oxobutan-2-yl)amino)-4-oxobutanoic acid (SVN) has been employed as soft container to modify the photochemical and photophysical behavior ... -
Pseudopeptidic fluorescent on-off pH sensor based on pyrene excimer emission: Imaging of acidic cellular organelles
Elsevier (2016)A pseudopeptidic compound comprising a central C2 symmetric bis(aminoamide) moiety derived from the amino acid serine and two pyrene groups at the ends, Et(SerPyr)2, has been efficiently prepared. In aqueous solution, it ... -
Pulsed laser fragmentation synthesis of carbon quantum dots (CQDs) as fluorescent probes in non-enzymatic glucose detection
Elsevier (2024-08-30)Pulsed laser fragmentation in liquid (PLFL) is one of the synthesis routes for producing high-purity carbon quantum dots (CQDs) with less toxic by-products in a straightforward system. The limited literature regarding the ... -
Recognition of Free Tryptophan in Water by Synthetic Pseudopeptides: Fluorescence and Thermodynamic Studies
WILEY-VCH Verlag GmbH & Co. KGaA (2014-06)Pseudopeptidic receptors containing an acridine unit have been prepared and their fluorescence response to a series of amino acids was measured in water. Free amino acids, not protected either at the C or the N terminus, ... -
Self-Assembly Controls Reactivity with Nitric Oxide: Implications for Fluorescence Sensing
American Chemical Society (2018)Three molecules containing the fluorophore 4-amino-1,8-naphthalimide (ANI) and showing different tendencies to self-assembly in aqueous environment have been prepared and fully characterized. The fluorescence emissions of ... -
Structure-performance relationships of four lysosomal markers used for the imaging of HT-29 cancer cells and a cellular model of lysosomal storage disease (Niemann-Pick C)
Elsevier (2022-03-12)Four new BODIPY derivatives with a potential tendency to aggregation have been synthesized and characterized by means of NMR techniques, mass spectrometry and UV–Vis/fluorescence spectroscopies. The objective of this study ...
