LMU's new Nano Institute on Königinstrasse was officially opened on 17. June 2019. Its research staff will seek novel ways of exploiting the unique properties of nanomaterials to enhance the efficiency of energy generation and storage.

Immortal quantum particles

Strong quantum interactions prevent quasiparticles from decay. Image: K. Verresen (TUM)

Decay is relentless in the macroscopic world: broken objects do not fit themselves back together again. However, other laws are valid in the quantum world: new research shows that so-called quasiparticles can decay and reorganize themselves again and are thus become virtually immortal.

Black nanoparticles slow the growth of tumors

The dark skin pigment melanin protects us from the sun’s damaging rays by absorbing light energy and converting it to heat. Scientists around Prof. Vasilis Ntziachristos managed to create melanin-loaded cell membrane derived nanoparticles, which improved tumor imaging in an animal model while also slowing the growth of the tumor.

Stable majorities

How could prebiotic information-bearing DNA sequences survive in the face of competition from a vast excess of shorter molecules with random sequences? LMU scientists now show that a relatively simple mechanism could have done the trick.

NIM member Erwin Frey holds Kavli Chair 2019

The NIM scientist Prof. Dr. Erwin Frey (LMU) receives the prestigious Kavli Chair of the Kavli Institute of Nanoscience of the TU Delft.

One transistor for all purposes

Be it in a mobile, fridge or plane - transistors are everywhere. But often they are specialized for only one current range. Prof. Thomas Weitz (NIM) and his team have now developed a nanoscopic transistor of organic semiconductor material that is working perfectly at low and high currents.

Force for activation

Tumor invasion and metastasis are major problems in the therapy of cancer patients. NIM scientists around Prof. Hermann Gaub and collaboration partners in Madrid and Heidelberg now elucidated the activation conditions for a key enzyme in this process – a step forward in the development of new therapeutic strategies.

Cells in a tight spot

Breast cancer cell squeezing across a thin constriction

Migrating cancer cells must overcome physical barriers such as tight pores in finely meshed tissues. A recent study by a team of NIM biophysicists provides a new theory to describe how cells manoeuvre such confining environments.

Happy about noise

White noise signal (Wikipedia)

Noise for physicists means nothing but trouble: unspecific signals, interfering frequencies and low
measurement sensitivity. Scientists from the Universities of Augsburg and Hannover now discovered that noise can be extremely useful – for example in quantum mechanics.

No support needed

For the development of new semiconducting devices, the properties of the material need to be clarified. Ideally, the analysis is done without supporting substrate distorting the measurements. The NIM scientists Prof Thomas Weitz and Prof Achim Hartschuh are now able to fabricate freely suspended ultrathin organic semiconductor films.

Valleytronics at room temperature

Essential in the development of new ultrathin information carriers is the stabilization of the excited state, which carries the information. The NIM physicists Prof Ursula Wurstbauer, Prof Alexander Holleitner and Prof Alexander Högele now found a tunable method, even at room temperature.

New EU consortium for new gene therapies

The NIM scientist Prof Ernst Wagner coordinates the working package “Tailor gene-delivery strategies” within the new EU project “UPGRADE: Unlocking Precision Gene Therapy”. Together with Dr Ulrich Lächelt he will optimize the non-viral delivery of new and precise gene-editing tools.

Models of life

Signal molecules (blue) spread in the artificial cell structure and allow communication through the membranes.

Friedrich Simmel und Aurore Dupin, researchers at the TUM, have for the first time created artificial cell assemblies that can communicate with each other. The cells, separated by fatty membranes, exchange small chemical signaling molecules to trigger more complex reactions, such as the production of RNA and other proteins.

Delayed adaptation favors coexistence

Soil bacteria must be able to adapt to varying environmental conditions. – But a new study by LMU researchers indicates that rapid adaptation can be counterproductive, while delayed adjustment facilitates coexistence of different species.

Antibiotic resistant bacteria are on rise. Help comes from their natural enemies, the bacteriophages. Students from LMU and TU München, also from the group of NIM-scientist Prof. Friedrich Simmel, have developed a new method for their production. Their project was awarded with the second place in the renowned global iGEM competition.

Rod-shaped bacterial cells normally divide by constriction midway along their long axis. LMU physicists have developed a theoretical model to explain how Myxococcus xanthus localizes the plane of division to mid-cell.

Biophysicists from Augsburg and Santa Barbara report in Physical Review E on the first successful outcome in the targeted dynamic positioning of nerve cells on a chip. The proven Augsburg surface acoustic wave technology now opens up new ways of understanding and influencing neuronal networks.

It’s getting hot in here, why don’t you change your twist
