The identification and quantification of biomarkers or proteins is a real challenge in allowing the early detection of diseases. The functionalization of the biosensor surface has to be properly designed to prevent nonspecific interactions and to detect the biomolecule of interest specifically. A multilayered nanoarchitecture, based on polyelectrolyte multilayers (PEM) and the sequential immobi...

H3PW12O40 (PW12) was immobilized over mesoporous alumina through the reaction of mesoporous alumina functionalized 3-aminopropyl triethoxy silane (3-APTES) and PW12. The surface properties of the functionalized nanocomposite was analyzed by a series of characterization techniques like elemental analysis, FTIR and XRD. XRD and adsorption–desorption analysis shows that the mesostructure of silica...

In this work, three surface functionalization processes have been studied: the spontaneous grafting fromdiazonium salts, the chemically induced grafting from diazonium salts and the chemically induced graftingfrom diazonium salts in presence of vinylic monomers (which is Graftfast). These processes work at roomtemperature, atmospheric pressure, in aqueous medium and without any ext...
