Near-field optical probes have been used to produce a subdiffraction-limited ob- servation area for fluorescence correlation spectroscopy (FCS) experiments on supported membranes. The design of a bent, etched fiber probe that is compatible with biological ...
Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotin ...
A review. The efficient anal. of the function of ion channels is an important task in many different fields ranging from (bio)analytics and drug-screening to nanoelectronics. Here, the modulation of the channel activity of a synthetic ligand gated ion chan ...
How membrane receptors transduce external signals across the membrane and activate intracellular processes is a key question for fundamental research and for therapeutic purposes. Reliable in situ investigations requiest to preserve the full biological act ...
The outer membrane protein OmpF from Escherichia coli is a member of a large family of b-barrel membrane proteins. Some, like OmpF, are pore-forming proteins while others are active transporters or enzymes. We have previously shown that the receptor-bindin ...
Gating of an artificial receptor was monitored for the first time by impedance spectroscopy in tethered lipid bilayer. Subnanomolar concns. of antibody were detected by modulation of the channel activity. The principle of gating by an antibody is particula ...
A rapid biological method for the determination of the bioavailability of naphthalene was developed and its value as an alternative to extraction-based chemical approaches demonstrated. Genetically engineered whole-cell biosensors are used to determine bio ...

The ability of organisms, or individual cells to sense and to react to different external and internal stimuli (light, hormones, odorants, taste) is crucial for their survival. I will report on our recent progress to investigate mol. signal recognition and ...
