Abstract
A molecule is separated from a liquid sample containing said molecule and at least one additional molecule having a larger hydrodynamic diameter than the hydrodynamic diameter of the molecule to be separated, by means of a separation device comprising a substrate, at least one circulation channel arranged in said substrate, and at least one nanotube associated with said molecule to be separated and formed on a free surface of the substrate. Separation is achieved by means of the internal channel of a nanotube, such as a carbon nanotube, presenting an effective diameter chosen in predetermined and controlled manner. The effective diameter of the internal channel is chosen such as to be larger than the hydrodynamic diameter of the molecule to be separated and smaller than the hydrodynamic diameter of the additional molecules of larger hydrodynamic diameters.
