    摘要： Described is a device comprising a substrate, and a quorum sensor array on the substrate. The quorum sensor array comprises quorum sensors that release signal molecules in response to one or more environmental signals being sense by the quorum sensors to thereby amplify the one or more environmental signals by causing a signal chain reaction in neighboring quorum sensors of the quorum sensor array. Each of the quorum sensors comprises a lipid multilayer structure. Also described is a method comprising providing data for changes in optical properties of at least part of the quorum sensor array in response to exposing the quorum sensor array to one or more environmental signals, and determining the presence of the one or more environmental signals based on the data.

    摘要： A method for detecting the presence of molecules includes bringing into contact with at least one optical grating comprised of a first liquid phase, a second liquid phase which cannot be mixed with the first liquid phase. The first liquid phase is arranged on a substrate in a form of periodic structures having a periodicity ranging from about 190 nm to about 10 μm. The molecules to be detected, which are capable of changing the optical characteristics of the at least one optical grating are added to the first liquid phase or to the second liquid phase either before, during or after the bringing step. The presence of molecules is detected by measuring a changed reflection or transmission of light at the at least one optical grating or a changing spatial course of the diffraction pattern as soon as the first liquid phase makes contact with the second liquid phase and with the molecules to be detected.

    摘要： A method for applying membrane lipids to a substrate includes providing a substrate and an ink reservoir having an ink including a membrane lipid. The tip of a scanning probe microscope is dipped into the ink so as to dispose the membrane lipid on the tip. The tip of the scanning probe microscope is brought into contact with a surface of the substrate. The tip is moved over regions of the surface so that the membrane lipid migrates from the tip of the scanning probe microscope onto the surface of the substrate in the regions and the membrane lipid organizes itself in the regions in a form of a single lipid layer or in a form of one or a plurality of mutually superposed lipid bilayers. The tip is removed from the surface of the substrate.
