Nanodevice For Weighing Individual Molecules

April 18, 2005

Physicists have created the first nanodevices capable of weighing individual biological molecules. This technology may lead to new forms of molecular identification that are cheaper and faster than existing methods, as well as revolutionary new instruments for proteomics.

According to Michael Roukes, professor of physics, applied physics, and bioengineering at Caltech and the founding director of Caltech’s Kavli Nanoscience Institute, the technology his group has announced this week shows the immense potential of nanotechnology for creating transformational new instrumentation for the medical and life sciences. The new devices are at the nanoscale, he explains, since their principal component is significantly less than a millionth of a meter in width.

Tiny Porphyrin Tubes May Lead to New Nanodevices

March 18, 2005

Sunlight splitting water molecules to produce hydrogen using devices too small to be seen in a standard microscope. That’s a goal of a research team from the National Nuclear Security Administration’s Sandia National Laboratories.

Sunlight splitting water molecules to produce hydrogen using devices too small to be seen in a standard microscope. That’s a goal of a research team from the National Nuclear Security Administration’s Sandia National Laboratories. The research has captured the interest of chemists around the world pursuing methods of producing hydrogen from water. Read the rest of this entry »


Nanotech device touted to replace transistors in computers

February 15, 2005

U.S. scientists have developed a layer of molecules just three-billionths of a meter thick that can help store data during a computing operation without using traditional semiconductors and some day could replace the transistor as the building block of all computers.

The technology could produce computers that are thousands of times more powerful than those produced today, Hewlett Packard researchers say in a paper published Tuesday in the Journal of Applied Physics.
