Microextraction Team

By R. Lucena
Rafael Lucena is a professor of Analytical Chemistry at the University of Cordoba since 2010. He is the secretary of the Research Institute of Fine Chemistry and Nanochemistry (IUNAN).
Up to date, Rafael has coauthored 112 scientific articles  (h-index: 34, Scopus), mainly related to sample treatment in analytical chemistry. He has co-edited one particular volume in Anal. Bioanal. Chem. journal and an e-book on the topic. Rafael has also directed 8 Ph.D. Thesis (two additional ones are under development) and several Master and Degrees Thesis in this field.
In 2011, he created Microextraction Tech as a useful resource for those researchers working in the sample treatment field.
Marisol Cárdenas is a Full Professor of Analytical Chemistry.  Currently, she is Vice-Chancellor of the University of Cordoba and the leader of the FQM215 Research Group.
Her research interests comprise microextraction techniques, including developing new approaches and synthesis of novel nanomaterials based on carbon, metallic nanoparticles, and polymers. She has co-authored 229 scientific articles that have been cited 7020 times (Source: Scopus), and her h-index is  48. She has co-supervised 18 Doctoral Thesis, 12 of them with European/international mention, and 4 with doctorate award.
She collaborated with the Blog Project from the beginning, and she has written several posts.

Guillermo Lasarte Aragonés is a postdoc researcher at the FQM-215 group. His thesis was focused on the application of CO2 to different microextraction alternatives, including the development of a new modality, called Effervescence-assisted microextraction and the application in this context for the first time of the so-called Switchable Solvent, a promising green alternative. In 2016, he joined the US Naval Research Laboratory (Washington DC) as Postdoc (George Mason University), at the Center for Biomolecular Science and Engineering and the Medintz Lab to expand the application of Analytical Techniques for the purification and characterization of hybrid (bio)nanomaterials and the study of newly designed Enzyme-QDs catalytic performance. In 2019, he returned to his scientific home at the University of Cordoba.
Guillermo has already participated in the blog written some posts related to his Thesis topics that you can read here and here.

Ángela I. López-Lorente is an Assistant Professor at the University of Córdoba. She has been Juan de la Cierva postdoctoral researcher at such department as well as Humboldt postdoctoral research fellow for two years at the Institute of Analytical and Bioanalytical Chemistry at Ulm University, Germany.
Her thesis was focused on the characterization and determination of nanoparticles. Her research topics have been extended to nanomaterials as analytical tools and the design of planar phases for microextraction and sensing platforms. She has co-authored more than 40 publications, several book chapters, and two books and co-edited a book on gold nanoparticles.
She has already joined the Microextraction Blog team.

Gold coated magnetic beads for electrochemical detection

By

This post summarizes an interesting article, recently accepted for publication in Analytical Chemistry, which presents an innovative use of magnetic beads. Researchers from the Osaka Prefecture University at Japan have proposed the synthesis of magnetic microbeads covered with a smooth gold layer that are used for the electrochemical detection of streptavidin (1). The synthesis, which is deeply described in the manuscript, consists of three well defined steps. First of all, the magnetic beads are introduced in a colloidal gold dispersion containing Au-nanoparticles (Au-NPs). Thanks to the opposite zeta potential of both materials (microbeads are negatively charged while Au-NPs present a positive charge), their assembly takes place by electrostatic interactions. However, the Au-NPs are not connected to each other and therefore the electrical resistance of the microbeads is too high. In a second step, the modified microbeads are dispersed in an aqueous medium containing HAuCl 4 as ...

Fabric phase sorptive extraction: a new generation green sample preparation strategy

by Dr. Abuzar Kabir, International Forensic Research Institute, Department of Chemistry and Biochemistry, Florida International University, Miami, Florida, USA Fabric phase sorptive extraction (FPSE), the most recent member of the sorptive microextraction family, has innovatively incorporated both solid phase microextraction (SPME) and solid phase extraction (SPE) techniques into a single technology platform. FPSE utilizes permeable natural/synthetic fabrics e.g., cotton, polyester, fiber glass supports to chemically bind sol-gel hybrid inorganic-inorganic sorbents. A 5 cm2unit of coated fabric (2.5 cm x 2.0 cm) is typically used as the extraction media which can be inserted directly into the sample container. Extraction of the analytes is generally expedited by using a magnetic stir bar to diffuse the analyts into the sample matrix so that rapid mass transfer from the sample matrix to the extraction medium takes place.Once the mass transfer equilibrium between the FPSE media and...

Rotating Disk Sorptive Extraction

By

by Prof. Dr. Pablo Richter, Department of Inorganic and Analytical Chemistry, Faculty of Chemical and Pharmaceutical Sciences, University of Chile. The modern trends in analytical chemistry promote efficiency and green technology in sample preparation. In this context, our research team developed a new technique in 2009 that is capable of extracting pollutants from liquid samples on a rotating PTFE disk with one surface coated with an extraction phase [1]. The disk has embedded a miniature magnetic rod, which allows rotation. We have termed this procedure rotating-disk sorptive extraction (RDSE). RDSE is currently available in two configurations. In the classic version (Figure 1), the extraction phase is a polymeric film adhered to one side of the PTFE disk (configuration 1). In this configuration, polydimethylsiloxane (PDMS), nylon and octadecyl (C18) have been used as the sorptive material for the extraction of low-polarity analytes (Log Kow between 3 and 7) [1-12]. However...
