Graphene enhanced plastics

Comparison of xGnP (graphene additive) to other nanocomposite additives.

Michigan state University is using the recent discovery that graphene is the strongest material ever and using graphene additives to make stiffer, stronger and lighter plastics.

The material – xGnP Exfoliated Graphite NanoPlatelets - can an either be used as an additive to plastics or by itself it can make a transformational change in the performance of many advanced electronic and energy devices,” Drzal said. “It can do so because it’s a nanoparticle with a unique shape made from environmentally benign carbon, and it can be made at a very reasonable cost.”

A major advantage of nanotech drug delivery is that multiple drug molecules can be combined on one nanoparticle so that one nanoparticle binds more strongly to the drug target than would the isolated drug molecules. Attaching 12 molecules of an HIV drug to a 2.0 nm diameter gold nanoparticle enabled the drug to prevent HIV infection in cultured patient cells. From a North Caroline State University News Release
“Failed HIV Drug Gets Second Chance with Addition of Gold Nanoparticles“:

Researchers at North Carolina State University have discovered that adding tiny bits of gold to a failed HIV drug rekindle the drug’s ability to stop the virus from invading the body’s immune system.
