Controlling neural exoskeletons more precisely with diamond sensors

01/02/2023

Brain-computer interfaces are able to restore some mobility to paralyzed people by controlling exoskeletons. However, more complex control signals cannot yet be read from the head surface because conventional sensors are not sensitive enough. A collaboration of Fraunhofer IAF, Charité – Universitätsmedizin Berlin, University of Stuttgart and other industrial partners has taken up this challenge.

New spray fights infections and antibiotic resistance

31/01/2023

The World Health Organization (WHO) ranks antibiotic resistance as one of the top ten threats to global health. A group of researchers at Chalmers University of Technology in Sweden are now presenting a new spray that can kill even antibiotic-resistant bacteria, and that can be used for wound care and directly on implants and other medical devices.

Novel microneedle bandage could save lives

26/01/2023

Secondary, uncontrolled bleeding from traumatic injury is the leading cause of death of Americans from ages one to 46. Amir Sheikhi, assistant professor of chemical engineering and of biomedical engineering at Penn State, has a plan to change that with a novel microneedle patch that can immediately stop bleeding after injury.

In the core of the cell: New insights into the utilization of nanotechnology-based drugs

25/01/2023

Novel drugs are based on drug transport using nanoparticles. Whether this drug transport is negatively influenced by an accumulation of blood proteins on the nanoparticle’s surface was not clarified for a long time. Scientists at the Max Planck Institute for Polymer Research have now followed the path of such a particle into a cell using a combination of several microscopy methods.

Better manufacturing and storage of retinal implants

24/01/2023

Age-related macular degeneration (AMD) is a degenerative eye condition. It is the most frequent cause of blindness in humans. In most cases, the chronic progression of the retinal condition is not curable. Fraunhofer researchers have now developed a new method for the production and clinical application of stem-cell-based retinal implants.

Bio-based flame retardants for bioplastics

18/01/2023

Researchers at the Fraunhofer WKI and the Fraunhofer IAP, in collaboration with industrial partners, have achieved initial success in the development of bio-based flame retardants in bioplastics. In the future, it could therefore be possible to utilize plastics in electronics and electrical engineering that consist of 100 percent bio-based materials.

Influenza or a cold? A new technology can help

11/01/2023

Is it COVID or the flu? A diagnosis without having to leave the house, just by looking at your smart home device? So far, no. But researchers at the Norwegian University of Science and Technology (NTNU) have developed a microresonator for the long-wave infrared spectrum that could enable new technologies, particularly for particle detection and spectroscopic chemical identification.

How optical microscopes allow detailed investigations of nanoparticles

10/01/2023

It sounds like trying to scan a vinyl record with a hammer: Light is actually too "coarse" to image small particles on the nanometer scale. However, in their project "Supercol" – funded by the European Union – scientists want to achieve just that: The investigation of nanoparticles with light.
