γ-Cyclodextrin-graphene quantum dots-chitosan modified screen-printed electrode for sensing of fluoroquinolones
(Springer, 2023)
An innovative electrochemical approach based on screen-printed carbon electrodes (SPCEs) modified with graphene quantum dots (GQDs) functionalized with γ-cyclodextrin (γ-CD) and assembled to chitosan (CHI) is designed for ...
One-pot synthesis of graphene quantum dots and simultaneous nanostructured self-assembly via a novel microwave-assisted method: impact on triazine removal and efficiency monitoring
(Royal Society of Chemistry, 2018)
One-step methods for fabricating green materials endowed with diverse functions is a challenge to be overcome in terms of reducing environmental risk and cost. We report a fast and easy synthesis of multifunctional materials ...
Design of a 3D interfacial SERS liquid sensing platform based on Au-nanobones for discrimination and quantitation of quercetin loaded nanoemulsions
(Elsevier, 2022)
Characterization, and discrimination between free quercetin and quercetin-loaded nanoemulsions (Q-NEs) are described, as well as the design of a plasmonic metal liquid platform for their quantitation. First, reproducible ...
Ionic-liquid-based microextraction method for the determination of silver nanoparticles in consumer products
(Springer, 2019)
A simple method to determine hazardous silver nanoparticles (AgNPs) based on ionic liquid (IL) dispersive liquid–liquid microextraction and back-extraction is described. This approach involves AgNP stabilization using a ...
Modified nanocellulose as promising material for the extraction of gold nanoparticles
(Elsevier, 2018)
Increasing number of engineering nanoparticles (NPs) in consumer products is unstoppable even after the toxic effect of metallic-based nanomaterials stated more than a decade ago; thus, selective methods for detecting ...
Discrimination between nanocurcumin and free curcumin using graphene quantum dots as a selective fluorescence probe
(Springer, 2020)
Accurate-controlled sized graphene quantum dots (GQDs) have been used as an analytical nanoprobe for detecting curcumin as a function of the photoluminescent quenching upon increasing concentrations of the analyte. Regarding ...
Carbon-based nanodots as effective electrochemical sensing tools toward the simultaneous detection of bioactive compounds in complex matrices
(Elsevier, 2020)
A comparative study about the electroanalytical performance of three types of carbon-based nanodots has been accomplished. They exhibit similar functionalities (oxygenated groups) but diverse size and core structure ...
Cyclodextrin-modified graphene quantum dots as a novel additive for the selective separation of bioactive compounds by capillary electrophoresis
(Springer, 2021)
Highly reliable separation and determination of various biologically active compounds were achieved using capillary electrophoresis (CE) based on β-cyclodextrin-functionalized graphene quantum dots (βcd-GQDs) as the ...
Glycerol photoreforming for photocatalytic hydrogen production on binary and ternary Pt-g-C3N4-TiO2 systems: a comparative study
(Elsevier, 2024)
Photocatalytic hydrogen production using two sacrificial agents (triethanolamine and glycerol) was conducted on several binary (Pt/TiO2 and Pt/g-C3N4) and ternary systems (Pt on a heterojunction between TiO2 and g-C3N4 ...
Innovaciones en sistemas de toma de muestras ambientales que empleen nuevas fases sorbentes para la preconcentración de contaminantes
(Universidad de Córdoba, UCOPress, 2022)
La obtención de información analítica de los compartimentos ambientales conlleva necesariamente la consideración de una etapa de muestreo y de tratamiento de muestra. El impacto que ambas tienen en la calidad de los ...
