Potential of composite materials in analytical sample preparation
(Universidad de Córdoba, UCOPress, 2025)The overexploitation and destruction of natural resources threaten the future of the new generations. In this complex scenario, citizens expect science to provide solutions that can solve or at least minimize this ecological ... -
Potential of hydrophobic paper-based sorptive phase prepared by in-situ thermal imidization for the extraction of methadone from oral fluid samples
(Elsevier, 2022)Paper-based sorptive phases (PSPs) are functional planar materials with a demonstrated potential in analytical sample preparation. This article describes the synthesis of a polyimide coated paper by an in-situ imidization ... -
Potential of supramolecular solvents for the extraction of contaminants in liquid foods
(Elsevier, 2009)Supramolecular solvents, which are water immiscible liquids consisting of supramolecular aggregates in the nano- and micro-scale regimes dispersed in a continuous phase, were assessed for the extraction of trace contaminants ... -

Preparation and evaluation of micro and meso porous silica monoliths with embedded carbon nanoparticles for the extraction of non-polar compounds from waters
(Elsevier, 2016)A novel hybrid micro and meso porous silica monolith with embedded carbon nanoparticles (Si-CNPs monolith) was prepared inside a fused silica capillary (3 cm in length) and used as a sorbent for solid-phase microextraction. ... -
Preparation of macroscopic carbon nanohorn-based monoliths in polypropylene tips by medium internal phase emulsion for the determination of parabens in urine samples
(Elsevier, 2019)A porous monolithic solid based on single-walled carbon nanohorns dahlia-like structure, produced from a medium internal phase emulsion (MIPE), was prepared in a polypropylene tip using UV energy. Thus, single-walled carbon ... -
Preparation of porous methacrylate monoliths with oxidized single-walled carbon nanohorns for the extraction of nonsteroidal anti-inflammatory drugs from urine samples
(Springer, 2017)In this study we have developed a poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate-co-oxidized single walled carbon nanohorns) (poly(GMA-co-EDMA-co-o-SWNHs) spin columns via photo-polymerization for the extraction ... -
Preparation, characterization and evaluation of hydrophilic polymers containing magnetic nanoparticles and amine-modified carbon nanotubes for the determination of anti-inflammatory drugs in urine samples
(Elsevier, 2020)Hydrophilic solids based on poly(2-hydroxyethyl methacrylate) (pHEMA) with embedded magnetic nanoparticles and amine-modified carbon nanotubes were synthesized by photopolymerization. For this purpose, an oil in water (O/W) ... -
Presence of diphenyl phosphate and aryl-phosphate flame retardants in indoor dust from different microenvironments in Spain and the Netherlands and estimation of human exposure
(Elsevier, 2018)Phosphate flame retardants (PFRs) are ubiquitous chemicals in the indoor environment. Diphenyl phosphate (DPHP) is a major metabolite and a common biomarker of aryl-PFRs. Since it is used as a chemical additive and it is ... -

Quantitative proteomic analysis of Pseudomonas pseudoalcaligenes CECT5344 in response to industrial cyanide-contain ing wastewaters using Liquid Chromatography- Mass Spectrometry/Mass Spectrometry (LC- MS/MS)
(PLOS, 2017)Biological treatments to degrade cyanide are a powerful technology for cyanide removal from industrial wastewaters. It has been previously demonstrated that the alkaliphilic bacterium Pseudomonas ps ... -
Quick and Sensitive Enantioselective Determination of Permethrin in Fruits and Vegetables by Combining Supramolecular Solvents and Chiral Liquid Chromatography-Tandem Mass Spectrometry
(ACS, 2020)Permethrin (PM) is one of the chiral insecticides most widely used around the world. The significant differential toxicity of its four enantiomers and its important adverse effects on human health highlights the need for ... -
Quick supramolecular solvent-based microextraction for quantification of low curcuminoid content in food
(Springer-Nature, 2013)There is a need to monitor the consumption of curcuminoids, an EU-permitted natural colour in food, to ensure that acceptable daily intakes are not exceeded, especially by young children. This paper describes a sensitive ...
