Studying a mouse model of Alzheimer's disease, neuroscientists at the Technische Universitaet Muenchen have observed correlations between increases in both soluble and plaque-forming beta-amyloid – a protein implicated in the disease process – and dysfunctional developments on several levels: ...
DNA origami puts a smart lid on solid-state nanopore sensors
04-24-2012
The latest advance in solid-state nanopore sensors – devices that are made with standard tools of the semiconductor industry yet can offer single-molecule sensitivity for label-free protein screening – expands their bag of tricks through bionanotechnology. Researchers at the Technische ...
UV femtosecond laser pulses analyze internal dynamics of individual molecules
03-07-2012
Nowadays, large laser systems provide ultra-short light pulses of very high intensity, which – in principle – allow the imaging of matter and its dynamics on atomic scales, down to a single molecule or a virus. However, current methods fall short in efficiency to overlap a target molecule in ...

The world’s strongest neutron beam is produced by a scientific instrument at the research neutron source FRM II (Forschungs-Neutronenquelle Heinz Maier-Leibnitz) at the Technischen Universitaet Muenchen (TUM). But that is not all: During the long maintenance break in 2011, the instrument PGAA ...
Energy saving chaperone Hsp90
01-18-2012
A special group of proteins, the so-called chaperones, helps other proteins to obtain their correct conformation. Until now scientists supposed that hydrolyzing ATP provides the energy for the large conformational changes of chaperone Hsp90. Now a research team from the Nanosystems Initiative ...
Targeted proton transfer within a molecule
12-15-2011
For a long time miniaturization has been the magic word in electronics. Dr. Willi Auwaerter and Professor Johannes Barth, together with their team of physicists at the Technische Universitaet Muenchen (TUM), have now presented a novel molecular switch in the journal Nature Nanotechnology. ...

The mouth-watering aroma of roasted cocoa beans — key ingredient for chocolate — emerges from substances that individually smell like potato chips, cooked meat, peaches, raw beef fat, cooked cabbage, human sweat, earth, cucumber, honey and an improbable palate of other distinctly ...
Speed detection of electrons in nanoscale photodetectors
03-14-2011
Carbon nanotubes have a multitude of unusual properties which make them promising candidates for optoelectronic components. However, so far it has proven extremely difficult to analyze or influence their optic and electronic properties. A team of researchers headed by Professor Alexander ...
Residual dipolar couplings unveil structure of small molecules
02-22-2011
Chemists at the Technische Universitaet Muenchen (TUM) and the Karlsruhe Institute of Technology (KIT) introduced a new method for identifying chemical compounds. The approach they used is an improvement on nuclear magnetic resonance (NMR) measurements – for decades one of the most successful ...

Carbon monoxide is highly toxic since it blocks the binding site for oxygen in hemoglobin. This very principle – a porphyrin ring with a central iron or cobalt atom that the poisonous gas attaches to – can be used to implement sensors to warn against carbon monoxide. Physicists headed by ...
