Abstract

A microfluidic component comprises at least one channel (2) delineated by a top wall (6) and a bottom wall (3) and two opposite side walls (4, 5). The distance (P) between the top wall (6) and the bottom wall (3) of the channel (2) is greater than or equal to 25 micrometers and first and second sets of nanotubes (9a, 9b) are respectively borne by the two opposite side walls (4, 5) for the component to present a particularly high ratio between the contact surface and the available volume and a limited overall surface size. In addition, the distance between the two opposite side walls (4, 5) is about a few micrometers and preferably comprised between 3 and 5 micrometers.
