Publication number: 20230175962Abstract: A sensor arrangement performs simultaneous measurement of optical and electrical properties of a dielectric medium to be investigated, as well as the analytes contained therein. The arrangement contains a field-effect transistor and a surface plasmon resonance sensor. The sensor arrangement further contains a sample chamber for receiving the dielectric medium, which sample chamber is arranged such that the optical and electrical properties of the dielectric medium can be recorded simultaneously. The gate electrode of the field-effect transistor forms the active surface and/or is connected to the active surface of the surface plasmon resonance sensor, and has charge carriers which can be caused to oscillate by use of electromagnetic radiation.Type: ApplicationFiled: April 13, 2021Publication date: June 8, 2023Inventors: Johannes Bintinger, Patrik Aspermair, Stefan Fossati, Roger Hasler, Ulrich Ramach, Ciril Reiner-Rozman, Jakub Dostalek, Wolfgang Knoll

Patent number: 7518010Abstract: The invention concerns lipids functionalized with a terminal C?C double bond which can be transformed into an anchor group for binding to a substrate surface. The invention further concerns lipids comprising such an anchor group for binding to a substrate surface. The invention also concerns self-assembled monolayers of lipids on substrates, in particular on silicon oxide substrates. The lipids and the lipid monolayers or bilayers containing these lipids can be used to produce biomimetic supported membrane systems. These membrane systems can be directly anchored on silicon microelectronic devices. After the optional incorporation of functional molecules such as membrane-associated proteins such systems can used for applications such as model systems for examining biological membranes, screening methods, sensors and bioelectronic devices such as biocomputers.Type: GrantFiled: June 7, 2006Date of Patent: April 14, 2009Assignee: Max-Planck-Gesellschaft zur Foerderung der Wissenschaften e.
