A photoinduced electron transfer-based nanoprobe as a marker of acidic organelles in mammalian cells
Springer (2013-07)Photoinduced electron transfer (PET)-based molecular probes have been successfully used for the intracelular imaging of the pH of acidic organelles. In this study, we describe the synthesis and characterization of a novel ... -
Characterization of amine stabilized CdSe/ZnS core–shell quantum dots by using triarylpyrylium dyes
Royal Society of Chemistry (2016-06-13)A new method to study the stabilizing primary amine ligands coordinated to the surface of CdSe/ZnS core–shell quantum dots has been developed. The method is based on the reactivity of fluorescent 2,4,6-triarylpyrylium dyes ... -
Designing biocompatible and multicolorfluorescent hydroxyapatitenanoparticles for cell-imaging applications
Elsevier (2019)In recent years, there has been a growing effort toward the synthesis, engineering and property tuning of biocompatible nanoparticles (NPs) that can be detected by confocal microscopy and then used as fluorescent probes. ... -
Determination of selective serotonin reuptake inhibitors in plasma and urine by micellar liquid chromatography coupled to fluorescence detection
(2015-06-23)Citalopram, paroxetine and fluoxetine are selective serotonin reuptake inhibitor (SSRIs) currently used in the treatment of psychiatric disorders. We present an analytical method using micellar liquid chromatography to ... -
Macro- and nanoscale self-assembled amino acid derivatives as reduction-sensitive and photoactive materials
Universitat Jaume I (2022-05-23)Amino acid-based systems are attractive for biomedical applications given their high biocompatibility and functionality. Amino acids self-assemble into various structures ranging from a few nanometers to hundreds of microns ... -
Photoluminescence Enhancement of CdSe Quantum Dots: A Case of Organogel–Nanoparticle Symbiosis
American Chemical Society (2012)Highly fluorescent organogels (QD–organogel), prepared by combining a pseudopeptidic macrocycle and different types of CdSe quantum dots (QDs), have been characterized using a battery of optical and microscopic techniques. ... -
Pyrylium salts for bioimaging, sensing and solid-state emission
Universitat Jaume I (2021-09-24)The thesis entitled "Pyrylium salts for bioimaging, sensing and solid-state emission" is structured in 7 chapters that cover different aspects related to several applications of pyrylium salts. Two chapters correspond to ... -
Quantum dot–polymethacrylate composites for the analysis of NOx by fluorescence spectroscopy
Elsevier (2012)A new type of hybrid materials composed by core–shell (CdSe/ZnS) quantum dots adsorbed on polymethacrylate surfaces has been synthesized and characterized, specially by means of time-resolved fluorimetry. The ability of ... -
Ratiometric fluorescence sensing of phenylalanine derivatives by synthetic macrocyclic receptors
Elsevier (2010)The supramolecular analytical behavior of eight pseudopeptidic fluorescent receptors (1a-c, 2a-c, 3, 4) has been studied. The receptors are either macrocyclic or open chain derivatives based on the naphthalene chromophore. ... -
Styrylpyrylium Dyes as Solvent-Sensitive Molecules Displaying Dual Fluorescence
Wiley (2017-08-31)A series of new molecules showing solvent-sensitive UV/Vis spectroscopic properties have been synthesized and characterized. The new compounds share a common 6-styryl-2,4-disubstituted pyrylium architecture, which allows ... -
Use fluorescence spectroscopy to study polymeric materials with porous structure based on imprinting by self-assembled fibrilar networks
American Chemical Society (2008)Different polymeric materials have been prepared from the organogels formed by a polymerizable methacrylic mixture (methyl methacrylate/ethylene glycol dimethacrylate, 1:1, w/w) and the macrocyclic pseudopeptide 1. The use ... -
Validation of a procedure to quantify oxolinic acid, danofloxacin, ciprofloxacin and enrofloxacin in selected meats by micellar liquid chromatography according to EU Commission Decision 2002/657/EC
Wiley (2017-08)The suitability of an analytical method to determine oxolinic acid, danofloxacin, ciprofloxacin and enrofloxacin in edible tissues, based on micellar liquid chromatogra- phy coupled with fluorescence detection, to be applied ...
