The NIM scientist Prof Heinrich Leonhardt and colleagues from LMU Munich and from Berlin have won the "m4 award" of the Free State of Bavaria. The researchers received the prize for their project "Tubulis Therapeutics", next generation antibody conjugates for tumor cell-specific drug delivery.

Successful NIM NanoDay

Already shortly after the opening of the NIM NanoDay on 10 September 2017 the Lichthof of the LMU was bustling with visitors. The young NIM scientists enthusiastically presented their research, people were enjoying scientific talks and physics comedy and the offered lab visits were completely booked and a great success.

ERC Starting Grant for Alexander Urban

NIM member Alexander Urban has received a Starting Grant from the European Research Council (ERC). In his ERC project the physicist is going to explore and further develop so called halide-based perovskites for use in LEDs and lasers.

To operate, insert dimers

Complex consisting of cGAS dimers and cytosolic DNA.

The presence of DNA in mammalian cell cytoplasm triggers an immune response by binding to a dimeric enzyme, which inserts between DNA double helices to form the “rungs” of a ladder-like structure, as the NIM scientist Prof Leonhardt and his team have now shown.

The color of the light emitted by an LED can be tuned by altering the size of their semiconductor crystals. LMU researchers have now found a clever and economical way of doing just that, which lends itself to industrial-scale production.

Controlled Release Society awards Ernst Wagner

NIM scientist Prof. Ernst Wagner has been honored by the Controlled Release Society with a membership in the "CRS College of Fellows". Wagner is coordinator of the NIM area "Biomedical Nanotechnologies" and specialized in the development and delivery of nucleic acid based therapeutics.

Chatting coordinates heterogeneity

Bacterial populations can, under certain conditions, react in a coordinated manner to chemical messages produced by a minority of their members, as a new theoretical study carried out by NIM biophysicists from LMU Munich shows.

Supramolecular materials with a time switch

Materials that assemble themselves and then simply disappear at the end of their lifetime are quite common in nature. NIM scientists and colleagues have now successfully developed supramolecular materials that disintegrate at a predetermined time – a feature that could be used in numerous applications.

Saving energy with a tiny spot of silver

In the future, computers are expected to run on light particles instead of electrons. To that end, researchers are testing the use of gold nanoparticle chains as light conductors. LMU scientists now demonstrate how a tiny spot of silver could save enormous amounts of energy in light computation.

Semiconductors as decal stickers

Put an end to error-prone evaporation deposition, drop casting or printing: Scientists from LMU Munich and FSU Jena have developed organic semiconductor nanosheets which they can easily remove from a perfect growth substrate and place onto other preferred substrates.

Funding for research network “SolTech” extended

The research network „Solar Technologies Go Hybrid“ (SolTech) will be funded with a total amount of 17 million Euros for an additional five years by the Free State of Bavaria. Among the members are numerous research groups of the NIM Area “Nanosystems for Energy Conversion” who highly benefit from the intensive exchange within the network.

ERC Grant for Thomas Carell

NIM member Prof. Thomas Carell has won an ERC Advanced Grant. In his new ERC project, “The Chemical Basis of RNA Epigenetics”, Carell will explore how and why organisms chemically modify the nucleoside subunits of the nucleic acids DNA and RNA.

The quickest route to the tip

According to a theoretical model developed by LMU physicists, in cell protrusions, cargo-transporting motor proteins often get in each other’s way. The upshot is that freely diffusing proteins reach the leading edge faster.

Unlocking the secrets of the Achilles’ heel

Transition from tendon to bone connected by collagen fibers

Walking, running, jumping – every movement of the foot stretches the Achilles’ tendon and the loads can approach ten times the body weight. But the connection between the heel bone and Achilles’ tendon withstands this challenge. Scientists at TU Munich including NIM member Prof. Andreas Bausch has now discovered why.

A new spin on electronics

Our computer technology is based on the transport of electric charge in semiconductors. This technology’s potential will be soon reaching its limits since the components deployed cannot be miniaturized further. NIM scientists and colleagues demonstrate an alternative: using an electron’s spin to transmit information.

Hairpins help each other out

The evolution of cells and organisms is thought to have been preceded by a phase in which informational molecules like DNA could be replicated selectively. New work shows that hairpin structures make particularly effective DNA replicators.

Shaken, but not stirred

A team of researchers led by NIM physics professor Immanuel Bloch has experimentally realized an exotic quantum system which is robust to mixing by periodic forces.

What holds the heart together

Our hearts beat a life long. With every beat our heart muscle contracts and expands. How this can work throughout an entire life remains largely a mystery. NIM scientists from TU Munich and a team from Vienna have now measured the forces acting between the building blocks titin and α-actinin which stabilize the muscle.

Lighting up ultrathin films

Based on a study of the optical properties of novel ultrathin semiconductors, NIM researchers have developed a method for rapid and efficient characterization of these materials.

Learning from nature

A novel carbon nitride-based polymer is capable of storing electrons energized by sunlight for hours and releasing them on demand. The system might provide the basis for the storage of solar energy in the future.

Ernst Haage Prize for Aliaksandr Bandarenka

NIM member Prof. Aliaksandr Bandarenka (TU Munich) was awarded the Ernst Haage Prize 2016. The prize is given jointly by the Ernst Haage foundation and the Max Planck Institute for Chemical Energy Conversion and endowed with 7.500 EUR. It honors young scientists for outstanding achievements in this research field.

Shaping up to make the cut

Before RNA copies of genes can program the synthesis of proteins, the non-coding regions are removed by the spliceosome. Munich researchers report that distinct conformations of a member of this molecular complex play a vital role in the process.

Genes on the rack

Physicists at LMU have developed a novel nanotool that provides a facile means of characterizing the mechanical properties of biomolecules. They constructed a molecular clamp out of artificial DNA strands that can be programmed to exert a defined force on a test molecule.

Tiny measuring device for humidity and solvent vapors

NIM scientists developed a measuring device which is only a few nanometers in size but fulfills two functions: it detects very low humidity levels and identifies vapors of organic solvents. The central part of the device is a stack of nanolayers.

Measuring forces in the DNA molecule

DNA normally has the structure of a double helix. Among other things, it is stabilized by stacking forces between base pairs. Scientists at the TUM have succeeded at measuring these forces for the very first time on the level of single base pairs. This new knowledge could help to construct precise molecular machines out of DNA.

Random walk into captivity

The cell’s internal skeleton undergoes constant restructuring. LMU physicists now show that its constituent proteins can be efficiently transported to their sites of action by diffusion – provided they can be arrested when they get there.

DNA dominos on a chip

Normally, individual molecules of genetic material repel each other. However, when space is limited DNA molecules must be packed together more tightly. This case arises in sperm, cell nuclei and the protein shells of viruses. An international team of physicists has now succeeded in artificially recreating this "DNA condensation" on a biochip.

A signal boost for molecular microscopy

Cavity-enhanced Raman-scattering reveals information on structure and properties of carbon nanotubes

Protein patterns – stubbornly stable

Control of the spatial distribution of specific proteins within cells is crucial for many biological processes. NIM researchers have now shown that, once such patterns have been set up, they are remarkably robust to changing conditions.

Magic carpet

NIM scientists and their colleagues have found a clever way to decouple organic nanosheets grown on metal surfaces. By intercalation of iodine atoms the “organic carpet” behaved almost as it was free-standing: Ideal conditions to transfer organic nanostructures from metal onto more suitable substrates for molecular electronics.

Live is motion

Any system in thermodynamic equilibrium is known to satisfy perfectly balanced forward and backward transitions between any two states. Living systems like cilia violate this principle. Thus, even stochastic fluctuations in such systems could be used to drive a small-scale engine. Picture: C. Hohmann (NIM), M. Leunissen (Dutch Data Design)

The LMU physicist Chase Broedersz and co-workers have developed a way to distinguish the random motions of particles in non-living molecular systems from the motility of active living matter.

The method affords new insights into fundamental biological processes.

Friedrich Simmel receives ERC grant

The NIM member Friedrich Simmel from the Physics Department of TUM won out in the latest round of ERC grants. His interdisciplinary project is at the interface of physics and biology. It would not have been possible just a few years ago. It is ambitious in trying to carve out new scientific grounds.

Mechanics of the cell

Living cells must alter their external form actively, otherwise functions like cell division would not be possible. At the Technical University of Munich (TUM) the biophysicist Professor Andreas Bausch and his team have developed a synthetic cell model to investigate the fundamental principles of the underlying cellular mechanics.

Efficiency of water electrolysis doubled

Water electrolysis has not yet established itself as a method for the production of hydrogen. Too much energy is lost in the process. With a trick researchers of the Technical University of Munich (TUM), the Ruhr University Bochum and Leiden University have now doubled the efficiency of the reaction.
