The dark skin pigment melanin protects us from the sun’s damaging rays by absorbing light energy and converting it to heat. This could make it a very effective tool in tumor diagnosis and treatment, as demonstrated by a team from the Technical University of Munich (TUM) and Helmholtz Zentrum München. The scientists 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.
Creating Blood Vessels on Demand

When organs or tissues are damaged, new blood vessels must form as they play a vital role in bringing nutrients and eliminating waste. This is the only way for organs and tissues to resume their normal function. At present, the injection of growth factors or genetic material into the tissue site of interest can trigger angiogenesis, i.e. the growth of new blood vessels from pre-existing vessels. In a study published in the journal Advanced Materials, scientists from the Universities of Freiburg and Basel led by Prof. Dr. Prasad Shastri show that stable angiogenesis can be achieved by simple hydrogel injection. Due to its mechanical properties, this hydrogel resembles a blood clot.

Quartz glass is the preferred material for applications that require long-term use because of its high chemical and mechanical stability and excellent optical properties. The engineer Prof. Dr. Bastian E. Rapp from the Department of Microsystems Engineering (IMTEK) at the University of Freiburg and his team have developed the Glassomer process, a method that enables scientists to shape glass like plastic. In the scientific journal “Nature Communication”, they recently presented a new application: They are now able to produce three-dimensional hollow structures in quartz glass.

A research team led by biophysical chemist Professor Edward Lemke has engineered a designer organelle in a living mammalian cell in a new complex biological translation process. The created membraneless organelle can build proteins from natural and synthetic amino acids carrying new functionalities. For example, scientists might incorporate fluorescent building blocks into proteins via the organelle that allow a glimpse inside the cell using imaging methods. The research work now published in Science was a collaboration of Johannes Gutenberg University Mainz (JGU), the Institute of Molecular Biology (IMB) and the European Molecular Biology Laboratory (EMBL).

Scientists at the University of Bremen have now developed a three-dimensional protein structure in the laboratory that could help to heal wounds in the future. It is conceivable that one day this network could be produced as a kind of “biological bandage” from the blood of the person who will use it. The development is now patent pending.

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

The INM - Leibniz Institute for New Materials has developed new processes with photochemical metallization and printing (gravure printing, inkjet printing) of transparent conductive oxides (TCOs), which are significantly more time- and cost-saving. These will be presented by the scientists at this year's Hannover Messe from 1 to 5 April at Stand C54 in Hall 5.
3D Printers to Produce Precisely Fitting Plastic Parts for Lightweight Construction

- Category
3D printers are becoming ever more important: they can be used to quickly produce the desired products. Researchers at Technische Universität Kaiserslautern are also working with this system: in order to optimize the printing result for plastics, they examine the conditions required during printing. In this context, the composition of the material also plays a role. With their fibre-reinforced plastic, they rely on fibres that are completely built into the plastic like a string. This is interesting, for example, for the lightweight construction of vehicles. They will present their work at the Hannover Messe from 1 to 5 April at the Rhineland-Palatinate research stand (Hall 2, Stand B40).

The INM – Leibniz Institute for New Materials presents hybrid inks for inkjet printing that contain metal nanoparticles coated with conductive polymers. The inks can be formulated in water and in other polar solvents and are suitable to print conductive structures on a range of substrates without any subsequent thermal or UV treatment. Standard metal inks require annealing after inkjet printing to become conductive. INM’s new inks obviate this step, making them compatible with many substrates including thin polymer foils and paper.
Touchscreens go 3D with Buttons that Pulsate and Vibrate Under Your Fingertips

By pulsing or vibrating on demand, smartphone screens can help users navigate through a menu or can guide a user’s finger to virtual on-screen buttons that can be created or removed wherever and whenever needed. Professor Stefan Seelecke and his team at Saarland University have developed a film that gives touchscreens a third dimension. The thin and extremely lightweight silicone film can adopt a variety of positions and shapes and can be made to execute a single pulse, a pushing motion, a sudden jolt or a prolonged vibration at a specific location on the screen. The polymer film also exhibits sensor properties and can therefore provide the device with an added sense organ.

Strong enough not only for use in impact protection systems in cars, but able to absorb the shock waves produced by a detonation. Those are just some of the properties shown by the metallic foams developed by materials scientists Stefan Diebels and Anne Jung at Saarland University. Their super lightweight and extremely strong metal foams can be customized for a wide range of applications. The inspiration for the new foam system came from nature: bones. Using a patented coating process, the Saarbrücken team is able to manufacture highly stable, porous metallic foams that can be used, for example, in lightweight construction projects.

Physicists at Saarland University have developed magnetic field sensors that are breaking sensitivity records and opening up a whole range of potential new applications, from non-contact measurements of the electrical activity in the human heart or brain to detecting ore deposits or archaeological remains deep underground. Professor Uwe Hartmann and his research team have developed a system that allows them to detect weak magnetic signals over large distances in normal environments (no vacuum, no low temperatures, no shielding), despite the presence of numerous sources of interference.
