Rhodopsin-transducin coupling was used as an assay to investigate a laterally patterned membrane reconstituted with a receptor and its G protein. It served as a model system to show the feasibility to immobilize G protein-coupled receptors on solid support ...
We report on a novel gas spectrometry technique using pyroelectric thin-him arrays. The 1 x 50 element arrays of PZT are integrated onto silicon using a membrane structure. The experimental characterization of the pyroelectric elements shows both high volt ...
Lipophilicity of compounds with therapeutic interest represents one of the most important physicochemical parameters in predicting and interpreting transport processes across biological barriers. This property is commonly measured as a drug | membrane part ...
Membrane proteins fulfill many central functions in the biological membrane. The insertion process of these proteins and their structure, which are intimately linked to their function, are not yet well understood. As a model we studied three proteins recon ...
The use of many plastic packaging materials such as PVC, PAN, etc. to protect food and beverages is restricted because of toxicity and recycling problems and there is a need for the development of new packaging materials with good gas barrier properties. P ...
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) imaging is employed to characterize the surface of patterned noble metal (Pt) and titania (TiO2) thin films deposited on oxidized silicon wafers. ToF-SIMS is used to follow the different process ste ...
Lateral force microscopy in the wearless regime was used to study the friction behavior of a lipid monolayer on mica. In the monolayer, condensed domains with long-range orientational order of the lipid molecules were present. The domains revealed unexpect ...

Effects of nanosecond electromagnetic pulses on metallic (Al) and semiconductor (Si, GaAs) surfaces were investigated exptl. in vacuum. For the surface c.d. 104-106 Wcm-2, an impulse desorption of ions was obsd. from adsorbed gaseous layers or deposited or ...
The membrane of human immunodeficiency virus type 1 (HIV-1) virions contains high levels of cholesterol and sphingomyelin, an enrichment that is explained by the preferential budding of the virus through raft microdomains of the plasma membrane. Upon deple ...
Structure and orientation of mols. are key properties of functionalized surfaces. Using time-of-flight secondary ion mass spectrometry (TOF-SIMS), here we investigate how to modulate these parameters upon the immobilization process varying the conditions o ...
