Carbon Nanohorn Suprastructures on a Paper Support as a Sorptive Phase
(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
(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
(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
(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 ... -
Coacervative extraction of Ochratoxin A in wines prior to liquid chromatography/fluorescence determination
(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
(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 ... -
Comparison of drying techniques for extraction of bioactive compounds from olive-tree materials
(MDPI, 2023)Olive tree vegetal materials are considered a powerful source for the isolation of bioactive compounds—mainly phenols and triterpenic acids. However, the high humidity content of them reduces their preservation and ... -
