Wrapping Up The Future
There is an old saying that if something it too good to be true then it is too good to be true. I suspect that we may be seeing a lot of this material in the near future whether we like it or not.
Just what the implications of this nanotechnology are when applied to food wrapping and the human body are unknown. When I look at some of the nasty rashes I have had from fancy dressings I am far from sure.

New Antibacterial Material for Bandages, Food Packaging, Shoes
A new form of paper with the built-in ability to fight disease-causing bacteria could have applications that range from anti-bacterial bandages to food packaging that keeps food fresher longer to shoes that ward off foot odor.
A report about the new material, which consists of the thinnest possible sheets of carbon, appears in ACS Nano, a monthly journal
Chunhai Fan, Qing Huang, and colleagues explained that scientists in the United Kingdom first discovered the material, known as graphene, in 2004. Since then, the race has been on to find commercial and industrial uses for graphene.
Scientists have tried to use graphene in solar cells, computer chips, and sensors. Fan and Huang decided to see how graphene affects living cells.
So they made sheets of paper from graphene oxide, and then tried to grow bacteria and human cells on top. Bacteria were unable to grow on the paper, and it had little adverse effect on human cells.
"Given the superior antibacterial effect of graphene oxide and the fact that it can be mass-produced and easily processed to make freestanding and flexible paper with low-cost, we expect this new carbon nanomaterial may find important environmental and clinical applications," the reports states.
