Component with microfluidic structures, method for the production and use thereof

A method of manufacturing a component having a microfluidic structure, which is carried out in a continuous manner and comprises the following steps:

• (a) applying a layer of a curable embossing lacquer to a bottom film,
• (b) embossing recesses in the embossing lacquer layer obtained in step (a) using an embossing tool,
• (c) partially curing the embossed lacquer layer embossed in step (b) to form a partially cured structured layer,
• (d) removing the embossing tool to form a bottom member comprising the bottom film and the partially cured structured layer,
• (e) applying a layer of a curable bonding lacquer to a cover film to form a cover member, the thickness of the bonding lacquer layer of the cover member being less than the embossing depth of the partially cured structured layer of the bottom member formed in step (d),
• (f) forming a composite of the bottom member obtained in step (d) and the cover member obtained in step (e), wherein the partially cured structured layer of the bottom member is placed on the bonding lacquer layer of the cover member so that the recesses of the partially cured structured layer of the bottom member are sealed by the bonding lacquer layer of the cover member to form cavities which form a microfluidic structure, and
• (g) curing the partially cured structured layer and the bonding lacquer layer of the composite obtained in step (f) to form covalent bonds between these layers, wherein the curable bonding lacquer is not partially cured before step (g), thereby obtaining the component having a microfluidic structure.
