Movie Shows Development of a Wound Dressing Research in Fast Motion


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):

Im Focus: How Cells in the Developing Ear ‘Practice’ Hearing

Before the fluid of the middle ear drains and sound waves penetrate for the first time, the inner ear cells of newborn rodents practice for their big debut. Researchers at Johns Hopkins report they have figured out the molecular chain of events that enables the cells to make “sounds” on their own, essentially “practicing” their ability to process sounds in the world around them.

The researchers, who describe their experiments in the Dec. 3 edition of the journal Cell, show how hair cells in the inner ear can be activated in the absence...

Im Focus: Climate study finds evidence of global shift in the 1980s

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.

Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...
