A surface modified substrate includes a substrate having a surface, a layer of nanoscale inorganic oxide particles disposed on at least a portion of the surface of the substrate, said layer of nanoscale inorganic oxide particles comprising sites bearing an electric charge of a first polarity, and a monolayer of a polymer disposed on a least a portion of the layer of nanoscale inorganic oxide particles, said monolayer of polymer comprising sites bearing an electric charge of a second polarity, wherein the second polarity is the opposite of the first polarity.

L'invention porte sur un substrat modifié en surface qui comprend un substrat ayant une surface, une couche de particules d'oxyde inorganique à échelle nanométrique disposées sur au moins une partie de la surface du substrat, ladite couche de particules d'oxyde inorganique à échelle nanométrique comprenant des sites portant une charge électrique d'une première polarité, et une monocouche d'un polymère disposée sur au moins une partie de la couche de particules d'oxyde inorganique à échelle nanométrique, ladite monocouche de polymère comprenant des sites portant une charge électrique d'une seconde polarité, la seconde polarité étant l'opposé de la première polarité.
