Models of life
2019-01-17 – Friedrich Simmel und Aurore Dupin, researchers at the Physics Department of 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.
Munich student team develops new production method for viruses that attack bacteria
2018-11-15 – Bacteria that become resistant to known antibiotics are on rise. A team of students from the Technical University of Munich (TUM) and Ludwig-Maximilians University (LMU) have developed a new method to produce bacteriophages, the natural enemies of bacteria, which can be used as alternative treatments for bacterial infections. The team took second place among over 350 teams in the renowned global iGEM competition.
Piecework at the nano assembly line
2018-01-19 – Scientists at the Physics Department of TUM have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories. The new research results appear as the cover story on 19th January in the renowned scientific journal Science.
Viral or bacterial? New test for infections
2017-11-16 – Increasing antibiotic resistance is a global problem. In order to avoid unnecessary medication with antibiotics, Munich students developed a test system that can efficiently distinguish between bacterial and viral infections. At the international iGEM competition they were awarded as 1st Runner Up in the category overgradute students.
TUM and MPG strengthen their partnership to promote young scientists
2017-09-04 – Starting in 2018 the Technical University of Munich (TUM) and the Max Planck Society (MPG) will join several partners to break new ground: at the Max Planck School “Physics, Chemistry and Construction of Life”, selected university students and Doctoral candidates will be taught by Germany’s best researchers in order to research the basic principles of living systems.
DNA dominos on a chip
2016-08-22 – 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 so-called DNA condensation on a biochip.
Maßgeschneiderte optische Materialien aus DNA: Licht modifizierende Nanopartikel
2012-04-29 – Im menschlichen Körper trägt ein Doppelstrang aus Desoxyribonukleinsäure-Bausteinen, die sogenannte DNA, die Erbinformation. Aus künstlichen DNA-Molekülen hat nun ein von Wissenschaftlern des Exzellenzclusters NIM geleitetes internationales Team nanostrukturierte Materialien hergestellt, mit denen sie maßgeschneidert sichtbares Licht modifizieren können.
