Patent ID: 8029863

Claim:
A method for fabricating a microfluidic component comprising at least one microchannel delineated by bottom and top walls and two opposite side walls, the method comprising: formation, in a surface of a substrate, of the bottom wall and of the two opposite side walls of said microchannel, formation of nanostructures filling said microchannel by in situ growth from a first layer of a metallic catalyst deposited on the opposite side walls and on the bottom wall of said microchannel, and formation of the top wall of said microchannel by positioning a cover on said surface of the substrate and sealing said cover on said surface, wherein a second layer of said metallic catalyst is also deposited on surface of the substrate designed to come into contact with the cover and sealing is performed before the nanostructures are formed by heat treatment forming an eutectic compound between metal of the second layer of the metallic catalyst and a material of the cover.
