The present invention relates to a method of conferring modified properties, e.g. modified physical and/or biochemical properties, to a metallic substrate surface, comprising at least two steps consisting in(i) a first step comprising at least exposing said substrate surface to a hetero-bifunctional anchoring molecule carrying at least a silane group and at least a A group,said A group being optionally introduced within said anchoring molecule via a preliminary functionalizing step, and (ii) a second step of exposing the substrate surface to a polymer carrying at least three groups A2 capable of reacting with A in a thiol-ene reaction,the number average molecular weight of said polymer being greater than 1 000 g/mol.
