The subject of the present invention is a process for aligning a macromolecule (macromolecules) on the surface S of a support, characterized in that the triple line S/A/B (meniscus) resulting from the contact between a solvent A and the surface S and a medium B is caused to move on the said surface S, the said macromolecules having a part, especially an end, anchored on the surface S, the other part, especially the other end, being in solution in the solvent A. The subject of the present invention is also a process for detecting, measuring the intramolecular distance of, separating and/or assaying a macromolecule in a sample in which a process of alignment according to the invention is used.
