The present invention relates to a method for functionalising fluid lines (1b) in a micromechanical device, the walls of which include an opaque layer. For this purpose, the invention provides a method for functionalising a micromechanical device provided with a fluid line including a peripheral wall (5) having a surface (2) outside the line and an inner surface (3) defining a space (1b) in which a fluid can circulate, the peripheral wall at least partially including a silicon layer (5a). The method includes the following steps: a) providing a device, the peripheral wall (5) of which at least partially includes a silicon layer (5a) having, at least locally, a thickness (e) of more than 100 nm and less than 200 nm, advantageously of 160 to 180 nm; c) silanising at least the inner surface of the fluid line; d) the localised, selective photo-deprotection on at least the inner surface of the silanised device by exposing the peripheral wall (5) at the point at which said wall has a thickness (e) of more than 100 nm and less than 200 nm, advantageously of 160 to 180 nm.
