Abstract: The invention relates to a measuring chip cartridge module conducting mobile multi-parameter analyzes of chemical and/or biological substances, comprising a sample inlet for the extraneous introduction of a sample substance into said measuring chip cartridge module, at least one separate reagent inlet for the extraneous introduction of reagents into said measuring chip cartridge module, a measuring chip, the surface of which—designed for sample analysis—at least partially restricts an analysis cell with two openings, such that a liquid surrounding said sample substance can pass into the analysis cell through a first opening for the sample analysis, as well as a channel system, in which said sample substance can be conveyed from said sample inlet to said analysis cell and said reagents can be conveyed from at least the one reagent inlet to said analysis cell, wherein said channel system has no solid reagents, preferably no other substances apart from air and/or inert gas, prior to the introduction of said sam

Abstract: The invention relates to a component, comprising a carrier made of a structurable material with at least one continues opening which is closed by a porous membrane, characterized in that the porous membrane protrudes from the surface of the component surrounding the continuous opening. In some embodiments, the component further comprises a carrier substrate, wherein a side of the carrier substrate which faces the component and the opposite side of the component preferably form a fluid channel, wherein the at least one continuous opening of the carrier preferably communicates on its open side with the fluid channel. The component according to the invention is suitable for the installation and electrochemical measuring of transmembrane proteins, preferably in lipid bilayers. The invention also proposes different methods for producing the component.

Abstract: The present invention pertains to a process for detecting one or more chemical or biological species, which can either react in a redox reaction or directly or indirectly generate a molecule, which can react in a redox reaction, wherein current generated by said redox reaction is detected at at least one electrode, comprising the following steps: 1. Positioning a quantity of the species or molecule, which quantity varies over time, on, at or in the vicinity of the at least one electrode within a period t1-t2, 2. switching the at least one electrode back and forth multiple times during the period t1-t2 between two different potentials, such that relative to a reference electrode, it assumes potentials that are in the range of the oxidation potential of said species or of said molecule or above it or in the range of the reduction potential of said species or said molecule or under it, as a result of which said species/said molecule is alternatingly reduced and oxidized, and 3.
