We present an analysis on the blurring, electrical and optical properties of nanostructures fabricated by stencil lithography and their application for biomolecular sensing. We analyze the effect of the stencil-substrate gap on the blurring, then we present the fabrication and electrical characteristics of nanowires on plastic substrates, and finally, we demonstrate the application of nanodots for...
Microarrays play a key-role in life sciences and in diagnostics by providing a powerful tool for high throughput parallel analysis of complex samples. We present a novel approach to create heterogeneous vesicle arrays with optimized interface chemistry and low unspecific response. Here, complexes of biotinylated single-stranded DNA and streptavidin are spotted onto a non-fouling biotinylated polymer...
We present a platform for the controlled patterning of nano-objects such as gold colloids in the micron and nanorange. We are separating the lithography step from the subsequent functionalization. This has many advantages among them the independence of the linkage chemistry and the lithography process and the possibility to position individual nano-objects. The lithography step is extreme UV interference...
Enzymatic biosensors are expected to play a key-role in bio techno logical and biochemical analysis as shown by the success of glucose sensors in diabetes treatment. The aim of this work is to develop a multiplexed electronic detection system for early cancer diagnostics. Therefore, various enzymes were adsorbed to differently modified surfaces. Electrochemical optical waveguide lightmode spectroscopy...
