Structured liquid repellent surfaces with location defined wettable subregions

摘要

The present invention relates to structured surfaces with elevations an average height of 50 nm to 10 nm, and a mean distance of 50 nm to 10 nm, a surface energy of the unstructured material, of less than 35 mn / m and wettable subregions and method for the production of such surfaces. Dollars a according to the invention, structured surfaces, for the production of sample carriers for the instrumental analytics of sample carriers with liquid guide systems (microfluidics), as a structured reaction site for reagents and analyte for diagnostic systems (lab on chip) or for the preparation of nano - or microtiter - sample carriers are used.
