Abstract
A process for the production of a device having a surface microstructure of wells or channels. In the process one or more steps of screen-printing the microstructure as a curable material onto a plastic substrate, and curing the material. Such a device is also obtained by applying onto a substrate a material that is polymerizable or depolymerizable by irradiation, applying a negative or positive resist photoresist respectively, irradiating the structure and removing the unpolymerized or depolymerized material.
Claims9
A process for the production of a device having a surface microstructure of wells or channels, which consists essentially of
- providing a structure by applying onto a plastics substrate a material that is polymerizable or depolymerizable by irradiation and wherein the material that is unpolymerized or depolymerized is soluble in an aqueous developing solution,
- irradiating the structure through a photomask, and
- applying an aqueous developing solution to the irradiated structure and removing the unpolymerized or depolymerized material to produce the surface microstructure of wells or channels.
