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):

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
