Polydopamine inner wall-coated hypodermic needle as microextraction device and electrospray emitter for the direct analysis of illicit drugs in oral fluid by ambient mass spectrometry
Véjar-Vivar, C.; Millán-Santiago, Jaime; Mardones, C.; Lucena, Rafael; Cárdenas, Soledad (Elsevier, 2022)In this article, polydopamine inner wall-coated hypodermic needles (PDA-HNs) are evaluated as both microextraction devices and electrospray ionization (ESI) emitters for determining selected illicit drugs (methamphetamine, ... -
Recent Advances in Extraction and Stirring Integrated Techniques
Cárdenas, Soledad; Lucena, Rafael (MDPI, 2017)The extraction yield of a microextraction technique depends on thermodynamic and kinetics factors. Both of these factors have been the focus of intensive research in the last few years. The extraction yield can be increased ... -
Recycling Oxacillin Residues from Environmental Waste into Graphene Quantum Dots
Soriano, M. Laura; Cárdenas, Soledad (MDPI, 2019)Of great concern are the residual antibiotics from dirt that can be found in farm soil and wastewater. This kind of emerging pollutant into engineered nanomaterials is riveting. This work proposes the elimination and ... -
Returning to Nature for the Design of Sorptive Phases in Solid-Phase Microextraction
Mafra, Gabriela; García-Valverde, María Teresa; Millán-Santiago, Jaime; Carasek, Eduardo; Lucena, Rafael; Cárdenas, Soledad (MDPI, 2019)Green analytical chemistry principles aim to minimize the negative impact of analytical procedures in the environment, which can be considered both at close (to ensure the safety of the analysts) and global (to conserve ... -
Silica nanoparticles–nylon 6 composites: synthesis, characterization and potential use as sorbent
Reyes-Gallardo, E.M.; Lucena, Rafael; Cárdenas, Soledad (Royal Society of Chemistry, 2017)Composite materials based on the combination of nanoparticles (NPs) and polymers have attracted much attention in recent years thanks to their positive characteristics. In this article an easy, cheap and green procedure ... -
Síntesis de membranas de poliamida 6 y nanocuernos de carbono mediante electrospinning para su posterior uso en la extracción de compuestos de distinta naturaleza
Reyes-Gallardo, E.M.; Alcudia-León, M.C.; Lucena, Rafael; De Clerck, K.; Cárdenas, Soledad (Universidad de Córdoba, 2017) -
Tunable Polarity Carbon Fibers, a Holistic Approach to Environmental Protection
García-Valverde, María Teresa; Ledesma Escobar, Carlos Augusto; Lucena, Rafael; Cárdenas, Soledad (MDPI, 2018)The pollution of environmental resources is an issue of social concern worldwide. Chemistry is essential for the design of decontamination strategies and analytical approaches to detect and monitor the contamination. ... -
Unmodified cellulose filter paper, a sustainable and affordable sorbent for the isolation of biogenic amines from beer samples
Díaz-Liñán, M.C.; Lucena, Rafael; Cárdenas, Soledad; López-Lorente, A.I. (Elsevier, 2021)While current trends in Green Analytical Chemistry aim at reducing or simplifying sample treatment, food usually comprises complex matrices where direct analysis is not possible in most cases. In this context, sample ... -
Wooden-based materials: Eco-friendly materials for direct mass spectrometric analysis and microextraction
Millán-Santiago, Jaime; Lucena, Rafael; Cárdenas, Soledad (Wiley, 2021)Lignocellulosic materials have arisen as a sustainable alternative in microextraction techniques during the last 10 years. As they are natural materials, their use fits into some of the principles of Green Analytical ...
