METHOD FOR PRODUCING A BILIPID LAYER, AND MICROSTRUCTURE AND MEASURING ASSEMBLY

摘要

The invention relates to a method for producing a bilipid layer above a microcavity that is open on one side, to a microstructure for examining lipid double layers and to a measuring assembly for use in this respect. The method for producing a bilipid layer above a microcavity that is open on one side comprises the following steps: filling the microcavity with an electrolyte solution; moving a fluid containing dissolved lipids in a first direction toward the microcavity; moving the fluid in a second direction away from the microcavity; monitoring the formation of the bilipid layer above the microcavity by detecting an impedance between a counter-electrode connected to the fluid and a measuring electrode which is disposed in the interior of the microcavity. The microstructure has a substrate in which at least one microcavity is formed, wherein at least one measuring electrode is disposed in the interior of the microcavity and wherein the at least one microcavity can be connected to a fluid duct such that a laminar fluid stream can flow over the microcavity in at least two different flow directions.
