Abstract

A method for biochemical analysis uses a micro-reaction array with at least two reaction chambers for materials which react together chemically or biochemically. The reaction chambers are smaller than 1 μl, the reaction chambers are filled together by throughflow, the chemical or biochemical reactions of the substances retained therein then occurs in the individual isolated reaction chambers, thus preventing an interference between the reactions in the individual reaction chambers and the reaction products remain enclosed in the relevant reaction chambers. In the system the planar array has at least two reaction chambers for substances, whereby the reaction chambers are closed with the goal of preventing an exchange of substances.
