Trials for in-vivo applications are subject to a degree of secrecy, but Neil McClelland, the UK Project Manager for Nanopool GmbH, describes the results as "stunning". "Items such as stents can be coated, and this will create anti sticking features - catheters , and sutures which are a source of infection, will also cease to be problematic." Promising, but Let's Wait and See I'm still waiting for more tests (real-world and lab) before getting too excited. But if it works as promised, this could be a new super-material like graphene, with multiple applications in tons of different fields. And if it really makes things more durable and reduces or removes the need for strong chemicals to clean something, it could have a pretty significant positive environmental impact. But it could also have unforeseen effects, so let's not rush to put this everywhere. Michael Graham Richard – Science & Technology.
