An ordered mesoporous material (OMM) type SBA-16 was synthesized from sol gel type reactions and the self-assembly of surfactants. Once SBA-16 was obtained, it was functionalized with APTES (3-aminopropyltriethoxysilane) on the one hand and with MEA (monoethanolamine) on the other. Subsequently, the characterization of these nanomaterials was carried out using Scanning Electron Microscopy (SEM), Energy Disperse Spectroscopy (EDS), Infrared Spectroscopy (FTIR), N2 adsorption-desorption and X-ray Diffraction (XRD). In addition, a biosensor was developed where the central channel was modified with the material obtained SBA-16 (MEA) and a commercial ELISA Kit (enzymatic immunoassay) was used for a quantitative determination of the mycotoxin T-2 and compared with the analytical results of our generated biosensor.

Alex Simioli, INTEQUI

Alex Simioli carries out research in the field of volatile organic compounds (VOCs) and particulate matter, all related to atmospheric pollution and its determination using gas chromatography and mass spectrometry techniques. He has a master’s degree in chemistry since 2022 from the National University of San Luis in which his final work was the determination of T2 toxin in samples of agri-food interest from a Biosensor. He has been a Chemical Analyst since 2015 from the National University of San Luis and since 2014 he has worked in the Environmental Measurements Laboratory at the Chemical Technology Research Institute (INTEQUI), which depends on the National University of San Luis and CONICET.
