A new type of paper with built-in resistance to pathogenic bacteria may be used in a large number of applications, from antibacterial bandages to packaging that extends the shelf life of food to shoes that prevent foot odor. A report on this new material consisting of the thinnest carbon sheets present is published in the American Chemical Society's "ACS Nano" monthly magazine.
Chunhai Fan, Qing Huang and colleagues explained that British scientists first discovered this material called graphene in 2004. Since then, the race to find commercial and industrial uses of graphene has begun. Scientists have tried to use graphene in solar cells, computer chips and sensors. Fan and Huang decided to study how graphene affects living cells.
So they made a piece of paper from graphene oxide and then tried to grow bacteria and human cells on it. Bacteria cannot grow on this paper, and it has almost no side effects on human cells. "Considering the excellent antibacterial effect of graphene oxide and its large-scale production and easy processing to produce independent and flexible paper at low cost, we expect this new carbon nanomaterial to find important environmental and clinical applications. ," the report said.
