Claim:
1. Microstructure apparatus for the measurement of molecular membranes, comprising a support substrate having an upper side top for supporting the membrane, at least one microcavity of the support substrate for receiving an electrolyte, wherein the microcavity is open upwards and ends in a microaperture in the upper side of the support substrate, wherein the microaperture has a first characteristic diameter D1, at least one electrode, which is at least partially arranged in the microcavity and which has a contact side for contacting an electrolyte, the contact side being arranged adjacent to the inner volume of the microcavity, characterized in that the contact side of the electrode has a characteristic diameter D2 being larger than D1, the microcavity comprises an upper cavity section, which is limited upwardly by the microaperture surface and which has a characteristic diameter D3 in a cross section and in that the microcavity comprises a lower cavity section located below the upper cavity section and which has a characteristic diameter D4 in a cross section of the lower cavity, wherein D4>D3, and the upper cavity section has a characteristic height H3 and the lower cavity section has a characteristic height H4, wherein H4 is less than H3.
