Patent ID: 8277599

Claim:
A process for joining, placing and fixing a first object on a second object using binding molecules, wherein at least one of the first and second objects is a silicon substrate, comprising: applying a binding molecule of formula I Y′—(X′) n —A′ (I) on a surface of the first object, applying a binding molecule of formula II Y—(X) n′ —A (II) on a surface of the second object, wherein: A and A′ are independently functional groups which make it possible to bond, at least by one covalent bonding, to the surface of a given object, wherein A and A′ are radicals capable of forming covalent bonds with surface silicon atoms on the first and second objects and, wherein at least one of A and A′ is a vinyl radical, X and X′ are independently aliphatic, linear, branched or cyclic spacers which may comprise one or more heteroatoms, or aromatic or heteroaromatic spacers, or which may consist of several aromatic or heteroaromatic rings and optionally consist of aliphatic chains alternating with aromatic or heteroaromatic groups, n and n′ independently have the value 0 or 1, Y and Y′ are independently functions capable of generating one or more bonds of noncovalent type, Y and Y′ being selected such that they are complementary to allow the creation of one or more noncovalent bonds, or being selected such that they can complex a metal atom or an identical metal compound; and bringing the first and second objects into contact with each other so that Y and Y′ are associated with each other through the one or more bonds of noncovalent type.
