Abstract

Disclosed herein are analytical aids having a surface coated at least partially with a hydrophilic coating, where the hydrophilic coating includes nanoparticles with silica structure and an average particle size in a range from about 1 nm to about 500 nm. Also disclosed are methods of producing the analytical aids, as well as using the analytical aids in, for example, a sampling device containing the at least partially coated analytical aid.
