Abstract

The invention relates to a nozzle for use in a device for administering a liquid medical formulation, to a method for producing the nozzle in the form of a microfluidic component and to a tool for producing microstructures of the microfluidic component. The nozzle is formed by a plastics plate with groove-like microstructures which are covered by a plastics cover on the longitudinal side in a fixed manner. The production method includes a moulding process in which a moulding tool is used, which moulding tool has complementary metal microstructures which have been produced from a semiconductor material in an electrodeposition process by means of a master component.
