Abstract

The invention concerns a method for fixing a biological molecule, associated with a specific binding site, on the surface of a support made of silica or metal oxide. The invention also concerns a surface functionalized by the method and the use of such a surface. The method is characterized in that it consists in: functionalizing the surface by cleaning, using at least a solvent or an oxygen plasma or any other process for forming alcohol groups on the support surface, to make it hydrophilic; contacting the biological molecule on said functionalized surface; and functionalizing the support by fixing the biological molecule specific binding site on at least one of the support alcohol groups. The invention is particularly useful in the field of biomedical diagnosis.
