The measure by which any conductor is judged is how easily, and speedily, electrons can move through it. On this point, graphene is one of the most promising materials for a breathtaking array of applications. However, its ultra-high electron mobility is reduced when you synthesize larger sheets of the material. Now this barrier to industrial…

KTH Royal Institute of Technology researchers have reported a nanoengineering innovation that offers hope for treatment of cancer, infections, and other health problems — conductive wires of DNA enhanced with gold which could be used to electrically measure hundreds of biological processes simultaneously. While DNA nanowires have been in development for some time, the method…

With recent advances, technology can be used to synthesize silk with similar mechanical properties as an actual spider’s. But applying this material to promising medical therapies for illnesses such as cancer requires that humans develop a capability that only arachnids or silkworms possess – the ability to control the formation of silk. A technique reported…

The strongest yet hybrid silk fibers have been created by scientists in Sweden using all renewable resources. Combining spider silk proteins with nanocellulose from wood, the process offers a low-cost and scalable way to make bioactive materials for a wide range of medical uses. Published in American Chemical Society Nano by researchers from KTH Royal…
