functional requirement for flexible objects, particularly for diagnostic test strips

摘要

Planar functional coating for use in analytical test strips is attached to coated object so it does not wrinkle on bending of object. Planar functional coating for use in at least one area of a flat, flexible object, which is not holohedrally bound to the object and in which no wrinkles form on the side with the coating after bending of the composite comprising the flexible object and coating, comprises one or more surface forming coating elements which are fixed to the flexible object so that a part of its surface opposite to the coated object surface is movable in the direction of curvature caused by bending of the object. Independent claims are included for: (1) preparation of the coating; (2) test strip comprising a flexible, flat carrier (optionally transparent or optionally containing an inspection opening) upon which one or more test areas are located next to each other. The test areas are loosely coated with a coating as above; (3) preparation of the test strip.
