Abstract

A chip and a method for producing the chip with a plurality of measurement regions which are provided with electrodes for electrically detecting reactions in which, in order to reliably separate the individual measurement regions from one another, a monolayer of a fluorosilane is formed on the chip surface which has strongly hydrophobic properties. Therefore, during spotting with a liquid, the drops of liquid applied by spotting can be reliably prevented from coalescing, and thus, causing mixing of the substances in the drops of liquid which are supposed to be immobilized in the measurement regions.
