Abstract:
1. A method for functionalizing a micromechanical device provided with a fluid line comprising a peripheral wall having a surface external to the line and an internal surface delimiting a space in which a fluid can circulate, the peripheral wall comprising at least partially a layer of silicon, wherein the method comprises the following steps: a) the provision of a device whose peripheral wall at least partially comprises a layer of silicon having, at least locally, a thickness (e) of between 100 and 200 nm exclusive, c) the silanization of at least the internal surface of the fluid line, d) the localized and selective photodeprotection on at least the internal surface of the silanized device by insolation of the peripheral wall at the point where it has a thickness (e) of between 100 and 200 nm exclusive.
