Carbon-based nanodots as effective electrochemical sensing tools toward the simultaneous detection of bioactive compounds in complex matrices
Montes, Cristina; Soriano, M. Laura; Villaseñor, M. Jesús; Ríos, Ángel (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
Pinilla Peñalver, Esther; Soriano, M. Laura; Contento, Ana M.; Ríos, Ángel (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 ... -
Design of a 3D interfacial SERS liquid sensing platform based on Au-nanobones for discrimination and quantitation of quercetin loaded nanoemulsions
Montes, Cristina; Soriano, M. Laura; Villaseñor, M. Jesús; Ríos, Ángel (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 ... -
Determinaçao simultânea de resíduos de cloralfenicol, trianfenicol e florfenicol em peite bovino por cromatografia electrocinética micelar
Pezza, Leonardo; Ríos, Ángel; Nozal, Leonor; Arce Jiménez, Lourdes; Valcárcel, M. (Sociedade Brasileira de Quimica, 2006)A micellar electrokinetic chromatographic method (MEKC) is described for determining residues of amphenicols(chloramphenicol,thiamphenicol and florfenicol) in bovine milk. MEKC is conducted by using a separation buffer ... -
Discrimination between nanocurcumin and free curcumin using graphene quantum dots as a selective fluorescence probe
Pinilla Peñalver, Esther; Soriano, M. Laura; Durán, Gema M.; Llorent-Martínez, Eulogio J.; Contento, Ana M.; Ríos, Ángel (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 ... -
γ-Cyclodextrin-graphene quantum dots-chitosan modified screen-printed electrode for sensing of fluoroquinolones
Bartolomé, Manuel; Soriano, M. Laura; Villaseñor, M. Jesús; Ríos, Ángel (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 ...
