Someone suffers second- or third-degree burns: The wound must immediately be dressed and the dressing is to be changed regularly.
A short movie made by the group of Prof. Dr.-Ing. Stephan Barcikowski (University of Duisburg-Essen) shows the development of a dressing that promotes wound healing – from the materials research laboratory until the first practical trial (in English).
Even small area burns can be delicate, because healthy skin is our largest and most effective barrier against pathogens. It is therefore essential to support the wound healing process and to fight germs at the same time. Some metal ions, such as zinc or iron are known to accelerate healing.
Currently, the challenge for research is to develop an appropriate substrate to release the active ingredients gradually. In addition, it must be ensured that the active ingredients are harmful to bacteria but harmless to the human body.
Technical Chemist Nina Million from University of Duisburg-Essen (UDE) has developed a wound dressing containing nano zinc during her master thesis and was awarded the prize for the best thesis in 2013 by the German Society for Biomaterials. She removed zinc oxide and iron oxide nanoparticles from solid targets by laser pulses and applied them in a sponge-like carrier material.
This so-called microgel is arranged like a network enclosing the particles. Applied to a wound, it gradually releases antibacterial ions, while the particles themselves remain inside the microgel. Recently, studies adjusting the dose and thus optimizing the composition were successfully completed on rats.
The development succeeded in collaboration with the DWI – Leibniz Institute for Interactive Materials in Aachen and Hannover Medical School. An approximately four-minute movie produced together with the “Beilstein Institute zur Förderung der Chemischen Wissenschaften“ in Frankfurt clearly reconstructs the development process – in terms of interviews, laboratory demonstrations and explanatory drawings.
"It was fun to make this film," says Million. "But I also realized how difficult it is to summarize and communicate our own research in just a few words."
She can be proud of the result „Laser rapid prototyping of bioactive materials for medical treatment“ (in English):

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
