1. A method for generating an artificially patterned substrate for stimulating crystallization of a biomolecule, comprising:
treating a basic substrate for providing an artificially patterned substrate, wherein said basic substrate has a surface;
arranging a grating at a predetermined distance to said surface and in a plane substantially parallel to said surface, the grating having a characteristic selected to generate a pattern of linear wells across said surface, wherein the pattern of linear wells has a gradient with respect to a pattern periodicity along a length and a width of said surface, and wherein the linear wells intersect;
exposing the substrate through the grating to X-ray radiation to generate a gradiential artificially patterned substrate having said gradient; and
performing said exposing according to X-ray interference lithography technology.
