It’s a good thing that the now eight-year-old son of Miklos Gratzl, a Case Western Reserve University biomedical engineer, got a splinter in his finger one day – at least for the sake of science. With apologies to his son – instead of an "Ouch!" moment, for Gratzl it was more of an "A-ha!" moment.
As he was removing it from his son’s finger, the splinter gave him an idea: Since it showed no open wound in the skin, he thought to himself that a sensor like a sliver would be ideal for all kinds of biomedical applications since the skin would heal very quickly above it and after that no track infection can occur.
The associate professor of biomedical engineering and researcher at the Case School of Engineering has developed for the first time a "sliver-sensor" – a fully functional, minimally invasive, microscopic new monitor that can be placed just under the skin and seen with the naked eye for very accurate, continuous examination of glucose level for diabetics and other bodily fluid levels – with the help of simple color changes.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
