Nature Nanotechnology, the journal that brings science and nanotechnology together at the nanoscale, is now in volume 2. The latest issue of this second volume covers real-time single-molecule imaging; magnetic resonance force microscopy; protein detection; nanotube growth; quantum information; multiple nanodot formation; and the use of nanoparticles to deliver DNA into plant cells.

This issue also contains a freely available review article on DNA nanomachines by Jonathan Bath and Andrew J. Turberfield (Nature Nanotechnology 2, 275 – 284; 2007) – currently one of the hottest topics in all of nanoscience and nanotechnology. Research on building synthetic molecular machinery from DNA is inspired by biological systems in which individual molecules act, singly and in concert, as specialized machines: our ambition is to create new technologies to perform tasks that are currently beyond our reach. DNA nanomachines are made by self-assembly, using techniques that rely on the sequence-specific interactions that bind complementary oligonucleotides together in a double helix.
