A method of photografting organic molecules to a metal oxide comprising: (a) contacting a substrate having a metal oxide layer on a surface thereof with an acrylate, derivative thereof or a photolabile functional group; and (b) exposing the metal oxide layer and the acrylate, derivative thereof or photolabile group to UV or visible radiation to form covalent bonds between the metal oxide and the acrylate, the derivative thereof or the photolabile. L'invention concerne un procédé de photo-greffage de molécules organiques sur un oxyde métallique comprenant : (A) la mise en contact d'un substrat ayant une couche d'oxyde métallique sur une surface de celui-ci avec un acrylate, un dérivé de celui-ci ou un groupe fonctionnel photolabiles; et (b) l'exposition de la couche d'oxyde métallique et d'acrylate, du dérivé de celui-ci ou du groupe photolabiles à un rayonnement UV ou visible pour former des liaisons covalentes entre l'oxyde métallique et l'acrylate, son dérivé ou le photolabiles.
