Abstract: provided is a method for manufacturing a mold element for the production of microarrays, including the following steps: (i) providing a planar base element having a first surface and a second surface opposite the first surface, (ii) providing a planar auxiliary element on the second surface, (iii) penetrating the base element from the first surface in order to form mold openings, and (iv) reversibly or non-reversibly entering the auxiliary element when penetrating the base element. Moreover, a mold element for the production of microarrays, including a planar base element having a first surface a second surface opposite the first surface, a planar auxiliary element arranged on the second surface, and several mold openings extending from the surface of the base element through the second surface of the base element.

Abstract: A shockwave source and generating device includes a ring shaped or cylindrical wave generator having a central axis for radiating shockwaves in an axial direction or radially towards a parabolic reflector so that any yet unreflected radiation from the generator is intercepted by the reflector and reflected towards a focal point on that axis.
