A method for fabricating silicone elastomer stamps with hydrophilic surfaces is provided. The concept of polymer grafting is used to produce the stamps. The stamps thus produced have the great advantage that grafting of a thin hydrophilic polymer on a hydrophobic PDMS surface can render PDMS stamps permanently hydrophilic. With such stamps it becomes possible to print aqueous or highly polar inks reproducibly over days and weeks.

A method and also a device is proposed for identification of a substance, preferably comprising biochemical molecules. In a first step a probe and said substance will be brought into contact, afterwards in a second step the probe and said substance will be withdrawn from each other, while measuring the value of at least one physical parameter characterizing the interaction between said probe and said substance and comparing said measured value with a reference value for identification.
