“…From the previous results, it is clear that the AFFINIMIP®SPE Estrogens cartridge shows less cross‐reactivity effect in both samples, which did not happen for Milli‐Q water. This may be explained by the fact already described in the literature that the ionic content of a sample may influence the retention in some MIPs .…”

In this work, we have compared the selectivity of two commercial molecularly imprinted polymers (AFFINIMIP®SPE Estrogens and AFFINIMIP®SPE Zearalenone) for the extraction of 12 estrogenic compounds of interest (i.e. 17α-estradiol, 17β-estradiol, estrone, hexestrol, 17α-ethynylestradiol, diethylstibestrol, dienestrol, zearalenone, α-zearalanol, β-zearalanol, α-zearalenol and β-zearalenol) from different water samples. High-performance liquid chromatography coupled with ion trap mass spectrometry with electrospray ionization was used for their determination. Results showed that although both molecularly imprinted polymeric cartridges were specifically designed for different groups of analytes (natural estrogens like estradiol in the first case and zearalenone derivatives in the second) they nearly have the same extraction performance (with recovery values in the range 65-101%) for the same analytes in Milli-Q water because of the cross-reactivity of the polymer. However, when more complex water samples were analyzed, it was clear that the behavior was different and that the AFFINIMIP®SPE Estrogens showed less cross-reactivity than the other cartridge. Validation of the proposed methodology with both cartridges revealed that the extraction was reproducible and that the final limits of detection of the proposed method were in the low ng/L range.

Recent advances in the application of capillary electromigration methods for food analysis and Foodomics

et al. 2015

View full text Add to dashboard Cite

This review work presents and discusses the main applications of capillary electromigration methods in food analysis and Foodomics. Papers that were published during the period February 2013-February 2015 are included following the previous review by Garcia-Cañas et al. (Electrophoresis, 2014, 35, 147-169). Analysis by CE of a large variety of food-related molecules with different chemical properties, including amino acids, hazardous amines, peptides, proteins, phenols, polyphenols, lipids, carbohydrates, DNAs, vitamins, toxins, contaminants, pesticides, residues, food additives, as well as small organic and inorganic compounds. This work includes recent results on food quality and safety, nutritional value, storage, bioactivity, as well as applications of CE for monitoring food processing. The use, among other CE developments, of microchips, CE-MS, and chiral CE in food analysis and Foodomics is also discussed.

Multidentate Anion Receptors for Binding Glyphosate Dianion: Structure and Affinity

et al. 2017

View full text Add to dashboard Cite

For the first time, the relationships between anion receptor structures and their glyphosate dianion (Gly2–) binding affinity have been investigated. For this purpose, 12 multidentate bis‐indolocarbazole, bis‐urea and bis‐carbazole based synthetic receptors were synthesized and their binding affinities towards Gly2– were measured in H2O/DMSO media (0.5 % to 20 % of H2O). Computational geometries, as well as 1D and 2D NMR experiments were used to elucidate the structures of the complexes formed on binding of Gly2–. As expected, binding affinity depends strongly on the spatial position of the binding moieties, which, in turn, depend on the spacer length and rigidity. However, the relationships are not straightforward and, in some cases, are counterintuitive. Evidence is presented that, for several receptors, binding occurs through the phosphonate moiety only. One of the receptors described here has, to our knowledge, the strongest affinity towards Gly2– ever reported.
