Carbon Nanohorn Suprastructures on a Paper Support as a Sorptive Phase

Ríos Gómez, Julia; Fresco-Cala, B.; García-Valverde, María Teresa; Lucena, Rafael; Cárdenas, Soledad (MDPI, 2018)

This article describes a method for the modification of paper with single-wall carbon nanohorns (SWCNHs) to form stable suprastructures. The SWCNHs form stable dahlia-like aggregates in solution that are then self-assembled ...

Carbon nanotube-modified monolithic polymethacrylate pipette tips for (micro)solid-phase extraction of antidepressants from urine samples

Fresco-Cala, B.; Mompó-Roselló, Óscar; Simó-Alfonso, Ernesto F.; Cárdenas, Soledad; Herrero Martínez, José Manuel; Herrero, José (Springer, 2018)

This work evaluates the potential of methacrylate monoliths with multi-walled carbon nanotubes incorporated into the polymeric network for the extraction of antidepressants from human urine. The method is based on a ...

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 ...

Changes in human sweat metabolome conditioned by severity of obstructive sleep apnea and intermittent hypoxemia

Castillo Peinado, Laura de los Santos; Calderón Santiago, Mónica; Jurado-Gámez, Bernabé; Priego-Capote, Feliciano (Wiley, 2023)

Obstructive sleep apnea (OSA) is a sleep disorder that has been associated with the incidence of other pathologies. Diagnosis is mainly based on the apnea–hypopnea index (AHI) obviating other repercussions such as intermittent ...

Coacervados y hemimicelas/admicelas como sistemas extractantes de alteradores endocrinos

García Prieto, Amalia (Universidad de Córdoba, Servicio de Publicaciones, 2009)

Investigación centrada en la consolidación de los sistemas supramoleculares (coacervados de micelas inversas de ácido decanoico y hemimicelas/admicelas de dodecilsulfato sódico, SDS) como sistemas extractantes de sustancias ...

Coacervative extraction of Ochratoxin A in wines prior to liquid chromatography/fluorescence determination

García-Fonseca, S.; Ballesteros-Gómez, A.; Rubio Bravo, Soledad; Pérez-Bendito, Dolores (Elsevier, 2008)

Coacervates made up of reverse micelles of decanoic acid were assessed as a new strategy for the simplification of wine sample treatment in the determination of Ochratoxin A (OTA). Simultaneous extraction/concentration ...

Combining data acquisition modes in liquid-chromatography–tandem mass spectrometry for comprehensive determination of acylcarnitines in human serum

Luque-Córdoba, Diego; Calderón Santiago, Mónica; Priego-Capote, Feliciano (Springer, 2022)

Acylcarnitines (ACs) are metabolites involved in fatty acid β-oxidation and organic acid metabolism. Metabolic disorders associated to these two processes can be evaluated by determining the complete profile of ACs. In ...
