Hydrogen opens the road to graphene... and graphane

An international research team has discovered a new method to produce belts of graphene called nanoribbons. By using hydrogen, they have managed to unzip single-walled carbon nanotubes. The method also opens the road for producing nanoribbons of graphane, a modified and promising version of graphene.

New patent: Template-synthesized DNA nanotubes

A method of forming DNA nanotubes composed entirely or predominantly from DNA that, The methods of the present invention form single layer or multilayer template-synthesized nanotubes where the bulk of the tube is composed of DNA, and the layers are held together by hybridization of complementary DNA strands. The DNA molecules making up these tubes may be varied as desired, and the DNA is capable of being released from the tube.
