The new stem cell-containing bio ink allows 3D printing of living tissue, known as bio-printing. The new bio-ink contains two different polymer components: a natural polymer extracted from seaweed, and a sacrificial synthetic polymer used in the medical industry, and both had a role to play.
Critical conditions associated with the blockage of blood vessels are one of the primary health concerns worldwide. The main objective of emergency assistance in such conditions is to effectively implement thrombolysis, i. e. to quickly dissolve the clot.
People with diabetes often suffer from wounds that are slow to heal and can lead to ulcers, gangrene and amputation. New research from an international group led by Min Zhao, professor of ophthalmology and of dermatology at the University of California, Davis, shows that, in animal models of diabetes, slow healing is associated with weaker electrical currents in wounds.
Light microscopes based on scattering, reflection and absorption, or a combination of these, have been a key enabling technology for the study of objects invisible to our eyes, especially in the field of biology. Many improvements have been made in the past to create state-of-the-art techniques capable of achieving unprecedented resolution and sensitivity albeit their cost.
Coronary or peripheral bypasses are the most frequently performed vascular operations. Although one million patients per year and around the world, undergo this intervention, its failure rate reaches 50 percent, because of poor vessel healing, leading to vessel graft occlusion.
An ultrathin film that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by an international team of nanomaterials researchers from the University of Illinois at Chicago and Korea University.
Australian researchers at the University of Adelaide have developed a method for embedding light-emitting nanoparticles into glass without losing any of their unique properties -- a major step towards 'smart glass' applications such as 3D display screens or remote radiation sensors.
SIRKA: this acronym stands for "sensor suit for individual feedback of physical activity". In a joint project, the DFKI is developing a suit designed to prevent problems with poor posture. Inertial sensors are integrated into a work overall. Physiotherapists are also meant to benefit from the results.
The trend towards miniaturization is progressing in medical technology. This in turn also means that electronics must be adapted to size relations, for example of implants. Smaller structures and components are in demand as never before. Thus, the demands on the technology and production simultaneously grow.
