Abstract: The present invention relates to an improved process for producing highly ordered nanopillar or nanohole structures, in particular on large areas, which can be used as masters in NIL, hot embossing or injection molding processes. The process involves decorating a surface with an ordered array of metal nanoparticles produced by means of a micellar block- copolymer nano-lithography process; etching the primary substrate to a depth of 50 to 500 nm, where the nanoparticles act as a mask and an ordered array of nanopillars or nanocones corresponding to the positions of the nanoparticles is thus produced; using the nanostructured master or stamp in a structuring processes. Also the finished nanostructured substrate surface can be used as a sacrificial master which is coated with a continuous metal layer and the master is then etched away to leave a metal stamp having an ordered array of nanoholes which is a negative of the original array of nanopillars or nanocones.

Abstract: The invention relates to an arrangement for the remote-controlled release of active ingredients which are located with a magnetic body in a cavity and which are released under the influence of heat. A substantially biocompatible device, which avoids unnecessary thermal and electromagnetic loads, is created by producing the heat required for releasing the active ingredients by rotating the body in the fluid.

Abstract: A capsule is capable of releasing at least one agent that is contained therein by heating at least one heating element under the effect of at least one alternating magnetic field at a defined point in a body, said capsule dissolving when entering in contact with a dissolving liquid. The capsule avoids getting stuck on stenoses while being thermally acceptable and favorable from the point of view of energy. In the capsule, the heating element is at least partially surrounded with a capsule part, material of which is provided with greater thermal resistance than the walls of common capsules used for medicaments.
