Robot Arm Places Atoms and Molecules With 100% Accuracy

From HPlus Magazine:

In a 2009 article in Nature Nanotechnology, Dr. Seeman shared the results of experiments performed by his lab, along with collaborators at Nanjing University in China, in which scientists built a two-armed nanorobotic device with the ability to place specific atoms and molecules where scientists want them. The device was approximately 150 x 50 x 8 nanometers in size — over a million could fit in a single red blood cell. Using robust error-correction mechanisms, the device can place DNA molecules with 100% accuracy. Earlier trials had yielded only 60-80% accuracy.

Hankering for molecular electronics? Grab the new NIST sandwich

From PhysOrg.com:

The sandwich recipe recently concocted by scientists working at the National Institute of Standards and Technology may prove tasty for computer chip designers, who have long had an appetite for molecule-sized electronic components - but no clear way to satisfy it until now.

Scientists invent 1.2nm molecular gear (A major advance)

This is a big deal (from PhyOrg.com:

Scientists from A*STAR's Institute of Materials Research and Engineering (IMRE), led by Professor Christian Joachim, have scored a breakthrough in nanotechnology by becoming the first in the world to invent a molecular gear of the size of 1.2nm whose rotation can be deliberately controlled. This achievement marks a radical shift in the scientific progress of molecular machines and is published in Nature Materials, one of the most prestigious journals in materials science.

Scientists Automate Molecular Evolution

Scientists Automate Molecular Evolution from PhysOrg.com

Under the control of a computer at The Scripps Research Institute, a population of billions of genes morphed through 500 cycles of forced adaptation to emerge as molecules that could grow faster and faster on a continually dwindling source of chemical fuel -- a feat that researchers describe as an example of "Darwinian evolution on a chip."
