Abstract
The invention relates to a device including a substrate and at least one biologically active substance bound to at least a part of the surface of this substrate, which is obtained by simultaneous or sequential reaction of said substrate and of said substance with a bifunctional coupling agent in which one of the functional groups is capable of being photoactivated and generates carbenes and is used to bind the coupling agent to the inorganic substrate and the other functional group is used to bind the coupling agent to the biologically active substance, in which said substrate is a covalent inorganic nitride.
