Abstract

An absorbing zone for establishing and/or maintaining fluid transport through or along at least one fluid passage is manufactured on the basis of a non-porous substrate having a surface, the non-porous substrate having projections substantially perpendicular to the surface, and the projections having a height, diameter and a distance or distances between the projections such, that lateral capillary flow of the fluid in the zone is achieved.
