Abstract:
A process for specific and direct manipulation of small quantities of matter on a solid-body surface,which comprises generating, with the aid of one or more acoustic surface waves generated by a surface-wave generator, an impulse along the solid-body surface, which interacts with at least one quantity of matter in order to cause movement of said quantity of matter on said surface in a first direction, said functionalization being achieved by modulation of wetting properties of parts of said solid-body surface to define at least one hydrophobic region and at least one region that is hydrophilic as compared with said hydrophobic region, or at least one lipophobic region and at least one region that is lipophilic as compared with said lipophobic region.
