摘要： In the method proposed, microparticles suspended in a liquid or droplets suspended in a liquid with which they are immiscible are shaped by high-frequency electric fields in a three-dimensional electrode array (11a, 11b, 11c, 11d, 11e, 11f) of a size in the micrometre or submicrometer range and subsequently consolidated by prior art chemical bonding procedures or by physical methods. The disposition, geometry and control of the electrodes determine the shape of the particles. The particles themselves must have a conductivity and/or relative dielectric constant lower than the solution surrounding them. For some, this can be achieved only at certain frequencies in the kHz and MHz band which are determined by the passive electrical properties of the particles and the surrounding solution. The particles or droplets are repelled by the electrodes so that they are shaped in the free solution without making contact with any surface and can then be consolidated. This makes it possible to shape micrometre- and submicrometre-size particles of the kind required in chromatography, affinity biochemistry and medicine, as well as for filter systems.

摘要： The aim of the invention is to produce thin metal coatings and such structures on substrate supports of different structures. The lateral expansion of a metallic coating on each support can be predetermined with micrometer and submicrometer precision. The disclosed method enables flat and three-dimensional structures to be produced on smooth, planar or curved surfaces such as those required to reproduce letters or drawings. The method does not use any stamp printing techniques.

摘要： The invention relates to, inter alia, a method for electrically contacting an object (30) surrounded by a membrane, using an electrode (10, 100). According to the invention, at least one electrode (100) having a conductive carrier (110) on which a plurality of nanoneedles (120) is arranged is used for the contacting process, adjacent nanoneedles being interspaced by a distance smaller than the size of the object, and the object is brought into contact with the nanoneedles.
