Stanford University scientists have achieved new, detailed understanding of how a polymer folds into a unique three-dimensional structure by using an “optical trap” to precisely unfold a functional RNA molecule.

Japanese scientists have succeeded in chemically attaching proteins specifically to the tips of multiwalled carbon nanotubes, avoiding contaminating attachments to the sides of the nanotubes.
An interview by Nanotechnology.com of the director of the Center for Nanoscale Chemical-Electrical-Mechanical Manufacturing Systems got our attention. I’d give you a URL for this interview but it doesn’t seem to be on the web, only in email. An excerpt: The molecular gate toolbit: This is a toolbit that uses efficient electrokinetic transport in long… Continue reading Top-down nanotechnology reaches downward
Fibers made from zinc oxide nanowires can generate electrical current from low frequency mechanical motion, like body movements.
In a virtuoso demonstration of nanotechnology, researchers used a scanning tunneling microscope (STM) to build walls of carbon monoxide molecules to confine electrons on a copper surface so that they resonate like a drum.
Two stories report new tools that should accelerate nanotech development by providing scientists with faster determination of molecular structures.
This nanotech electronic device is not nanoscale, but all of the transistors are made from parallel arrays of thousands of nanotubes to demonstrate the potential of single-walled carbon nanotubes in advanced electronics.
French nanotech researchers have used theory to increase the precision of carving with electron beams enough to remove individual atoms from single walled carbon and boron nitride nanotubes.
Tetrahedrons made from DNA that extend and shorten in response to added short strands of DNA may provide new nanotech methods of drug delivery, but may present even more exciting possibilities for atomically precise functional nanosystems.
In a major nanotech advance in constructing designer materials, DNA has been used to assemble gold nanoparticles into three-dimensional crystals.
