A lipopeptide, carrying the antigenic peptide segment 135-154 of VP1, one of the capsid proteins of the picornavirus which causes foot-and-mouth disease in cattle, was investigated in lipid monolayers on the water surface and on hydrophobic solid supports. ...
The fabrication and application of photoplastic scanning force microscopy (SFM) probes has been demonstrated. Simple molding and replication techniques, inexpensive photoplastic material, reusable molds and several layers per probe make it a very attractiv ...
We have developed an ultra-stable low temperature scanning tunneling microscope (LTSTM) for application in atomic scale spectroscopy and atom manipulation experiments. The design is based on the Besocke type microscope allowing the installation of the LTST ...
Ag(111) surface state electrons have been confined in symmetric and asymmetric Fabry-Perot resonators formed by two atomically parallel step edges. The local density of states in the resonators has been measured by means of low-temperature scanning tunneli ...
An amperometric microsensor for the detection of trace metals in the low or sub nanomolar range is presented. It is obtained by successively evaporating iridium (2000 Å) and Si3N4 (2000 Å) on a silicon wafer, followed by a photolithographic pattering proce ...
The recent development of temperature controlled scanning tunneling microscopy opened the door to a fascinating new world on the nanometer scale. The atomic scale information obtained provides unprecedented insight into the kinetics of surface phenomena su ...
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 ...

A simple method has been developed for the prodn. of Au surfaces which are uniformly flat over large areas. Si wafers serve as substrates for the evapn. of thin Au layers. A glass slide glued onto the Au film allows successful sepn. of the Au layer from th ...
In a recent paper, a new class of synthetic lipids, which self-assemble to form monolayers on gold surfaces, was introduced. The addn. of a monolayer of phospholipids to these layers results in robust supported lipid bilayers designed to reconstitute trans ...
Surface chemical composition and topography of Pt-SnO2 thin films grown by radiofrequency (rf) reactive sputtering on two different Al2O3 substrates (rough and mechanically polished) were investigated by x-ray photoemission spectromicroscopy (XPSM) and ato ...
