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: The invention relates to a method for producing microstructures, the method including providing a planar mold element, which includes at least one mold opening for the microstructure to be produced, wherein the at least one mold opening has a first opening and a second opening; providing a first formulation at the second opening; generating a negative pressure in the mold opening; and taking up the first formulation through the second opening into the mold opening on account of the negative pressure in the mold opening. The invention further relates to a system for producing microstructures.

Abstract: The invention relates to a method for producing a mold element for producing micro-arrays. First, a planar base element, in particular in the form of a film, is provided. Recesses are made in, in particular embossed into, an upper face of the element. The recesses are opened on a lower face of the base element in particular by using laser radiation. The invention also relates in particular to a mold element produced by means of this method, which mold element has recesses like the base element. Each of the recesses has openings in the lower face of the base element.
