Biofunctional surface

The objective of this research line is to obtain biofunctional surfaces combining inorganic materials and organic functionalization using wet chemistry processes. The processes developed are very varied and include, in particular, thin-layer deposition by sol-gel route, hydrothermal synthesis of nanowires, assembly of unidimensional nanostructures by liquid filtration to form nanowire networks (nanonets), and surface functionalization. Examples of materials currently under studies are: very high aspect ratio ZnO nanowires, silicon nanonets, ZnO nanonets, functionalization with silane for biomolecule grafting. Such materials are studied for further integration into functional devices such as electronic devices (transistors) or sensors.
