Application of green zero-valent iron nanoparticles to the remediation of soils...
Machado, S.; Stawiński, W.; Slonina, P.; Pinto, A. R.; Grosso, J. P.; Nouws, Henri P. A.; Albergaria, José Tomás; Delerue-Matos, CristinaZero-valent iron nanoparticles (nZVIs) are often used in environmental remediation. Their high surface area that is associated with their high reactivity makes them an excellent agent capable of transforming/degrading contaminants in soils and waters. Due to the recent development of green methods for the production of nZVIs, the use of this material became even more attractive. However, the knowledge of its ca...
An electrochemical deamidated gliadin antibody immunosensor for celiac disease ...
Neves, Marta M. P. S.; González-García, María Begoña; Nouws, Henri P. A.; Costa-García, AgustínThe first electrochemical immunosensor (EI) for the detection of antibodies against deamidated gliadin peptides (DGP) is described here. A disposable nanohybrid screen-printed carbon electrode modified with DGP was employed as the transducer's sensing surface. Real serumsampleswere successfully assayed and the results were corroborated with an ELISA kit. The presented EI is a promising analytical tool for celia...
Carbon surfaces for the oxidative quantification of pravastatin: glassy-carbon ...
Neves, Marta M. P. S.; Nouws, Henri P. A.; Delerue-Matos, CristinaThe electrooxidative behavior of pravastatin (PRV) in aqueous media was studied by square-wave voltammetry at a glassycarbon electrode (GCE) and at a screen-printed carbon electrode (SPCE). Maximum peak current intensities in a pH 5.0 buffer were obtained at +1.3 V vs. AgCl/Ag and +1.0 V vs. Ag for the GCE and SPCE surface respectively. Validation of the developed methodologies revealed good performance charact...
Square-wave adsorptive-stripping voltammetric detection in the quality control ...
Nouws, Henri P. A.; Delerue-Matos, Cristina; Barros, Aquiles A.; Rodrigues, José A.; Santos-Silva, Alice; Borges, FernandaElectroanalytical methods based on square-wave adsorptive-stripping voltammetry (SWAdSV) and flow-injection analysis with square-wave adsorptive-stripping voltammetric detection (FIA-SWAdSV) were developed for the determination of fluoxetine (FXT). The methods were based on the reduction of FXT at a mercury drop electrode at -1.2 V versus Ag/AgCl, in a phosphate buffer of pH 12.0, and on the possibility of accu...
