Graphene (a sheet of carbon just one atom thick) can be successfully p-doped with boron, according to new experiments by researchers at Columbia University in the US. The result means that the carbon material can be both electron- and hole-doped, something that is important for advancing real-world graphene-based electronics. B dopants in graphene Chemical doping can be used to add or remove electrons from a material. Two years ago, a team led by Abhay Pasupathy showed that graphene could be…Continue

Researchers from the University of Florida and Hunan Univeristy developed DNA-directed silver nanoparticles (Ag NPs) grown on graphene oxide (GO). These so called Ag@dsDNA@GO composites act as antibacterial agents, decreasing X. perforans (a model plant pathogenic bacterium) cell viability in culture and on plants.
In a greenhouse experiment they applied this material on tomato transplants and they reported significant reduction of disease caused by bacterial spot compared to the…
