Peripheral artery diseases and injuries to tissue reduce the amount of oxygen that reaches the affected muscles. Such ischemia is difficult to treat, as new vessels are required to carry more oxygen into damaged tissues. Stem cells derived from...
Manufacturing artificial red blood cells may turn out to be significant in treating a number of diseases and conditions. This has been tried in the past by a number of teams, but some important functions were missing in every design. Now, a...
Precise delivery of therapeutic drugs into diseased tissue remains a challenge in a variety of cases. Tumors can be hard to seed with chemo agents, particularly when the blood flow is not favorable for delivery. Now, researchers at the Max...
Researchers at the Max Planck Institute for Intelligent Systems in Germany have developed powerful nanopropellers that can be steered into the interior of cells to deliver gene therapy. The magnets that these devices, each about the size of a...
Researchers at the Korea Basic Science Institute, Korea Research Institute of Chemical Technology, and collaborators have published an article on the development of graphene-based test for SARS-CoV-2, the virus causing COVID-19, from nasopharyngeal...
The development of biomaterials for orthopedic applications is a crowded space with several large and small companies designing innovative materials. One approach is the use of these materials to deliver therapeutic proteins that enhance healing....
A team of scientists, based at Swiss Federal Institute of Technology Lausanne (EPFL) with collaborators at Ulm University in Germany, University of Modena and Reggio Emilia in Italy, and MIT, have developed custom nanoparticles for...
Stick-on strain sensors that can accurately measure the flexion of joints, big and small, have turned out hard to make. Piezoresistive devices tend to have a delayed response and are not stable in the long-run, while capacitive sensors are not...
While current concern is all about the COVID-19 virus that originated in China and spread around the world, this pathogen will eventually disappear. Escherichia coli (E. coli) bacteria, though, is with us for the long run and it can cause just...
A myriad of different therapeutic, diagnostic, and research-oriented nano-scale devices and molecules have been developed to work inside living cells. While many of these particles are very effective at what they do, it is often the difficulty...
Researchers at the City University of New York and Northwestern University have developed a printer capable of creating highly detailed surfaces precisely loaded with a variety of organic and biological molecules. The technology allows the...
