Sheet-like material with hydrophilic and hydrophobic egions and their production

摘要

Sheet-like material in particular for use in biosensors and diagnostic strips composed of a substrate material on whose upper side at least one hydrophilic region and at least one hydrophobic region are present and arranged alongside one another, where the contact angle of the hydrophilic region with water is smaller than 30° and the contact angle of the hydrophobic region with water is greater than 90°.
