X-Message-Number: 30881 From: "Gina Miller" <> References: <> Subject: The Nanogirl News~ Date: Sun, 20 Jul 2008 22:58:46 -0700 The Nanogirl News July 20, 2008 National Nanotechnology Initiative Amendments Act enters U.S. Senate. U.S. Senators John Kerry and Olympia Snowe this week introduced the National Nanotechnology Initiative Amendments Act of 2008. The legislation was passed by the House of Representatives last month. The legislation aims to toughen the National Nanotechnology Initiative (NNI) by increasing its commitment to environmental health and safety research. Sens. Inouye, Stevens, Pryor, Smith, and Wyden have co-sponsored the bill. "Nanotechnology is a huge part of America's future, but it'll never take off if people don't trust that it's safe," said Sen. Kerry. "As we begin to further understand the immense capacity of this technology to improve our quality of life, public health and environmental safety must be top priorities."

An electronic circuit 100 times smaller than a hair, could help astronomers shed light on the universe's creation. The experimental device, developed by a team of physicists from NASA and several universities, is potentially 100 times more sensitive than existing "bolometers" or detectors of infrared and submillimeter waves-so sensitive that it can detect even a single photon of infrared light. This represents a significant breakthrough for scientists who hope to use such technology in space-borne telescopes to measure the invisible light that makes up 98 percent of light emitted since the "big bang."

In the clinical trial, the tumor response rate was nearly double for patients who received Abraxane compared to those who received solvent-based paclitaxel.

Spinning motion of a molecular rotor detected...Nanoscience has produced components for molecular-scale machines. One such device is a rotor, a movable component that rotates around an axis. Trying to observe such rotational motion on the molecular scale is an extremely difficult undertaking. Japanese researchers at the Universities of Osaka and Kyoto have now met this challenge. As Akira Harada and his team report in the journal Angewandte Chemie, they were able to get "snapshots" of individual molecular rotors caught in motion. As the subject of their study the researchers chose a rotaxane. This is a two-part molecular system: A rod-shaped molecule is threaded by a second, ring-shaped molecule like a cuff while a stopper at the end of the rod prevents the ring from coming off.

Purdue University is operating a virtual environment that enables scientists and engineers to interpret raw data collected with powerful instruments called dynamic atomic force microscopes. The online tools, believed to be the first of their kind for the instruments, represent a research trend, with tools for other applications also being developed, said Arvind Raman, a Purdue professor of mechanical engineering.

Conventional wisdom holds that a watched pot never boils and while "never" might be an exaggeration, most of us can agree that it takes longer than we'd like. However, researchers at the Rensselaer Polytechnic Institute have discovered that by coating the inside of a pot with a microscopic layer of copper nanotubes-which under appropriate magnification make the surface of the cooking vessel look hairy-they can increase the efficiency of energy transfer from the pot to the water it holds by an order of magnitude.

Carbon nanotubes that act like miniature radio receivers can detect and weigh individual gold atoms, according to a new study from the University of California, Berkeley. Researchers say that the sensors could one day be used to detect individual biomolecules, such as proteins, which might be employed to monitor the air for small traces of bioterror agents, or for rapid bedside diagnostics on unfiltered blood samples.

As nanomachines move beyond just prototypes, a potential industry of microscopic mass production awaits its own Henry Ford to make it a reality. In anticipation of this demand, researchers at a nanotech lab at UCLA are mass-producing billions of customizable microparticles using a machine normally found in the microchip fabrication industry. Lead by Dr. Thomas Mason, the team has created microscale letters to illustrate the possibilities of this new process.

Khademhosseini and a group of researchers at MIT and Harvard have come up with a simple two-step process to make the living Legos self-assemble. Their...relies on the basic fact that water and oil don't mix. When water is dropped into a pool of oil, it will form a sphere, the shape that minimizes its interaction with the oil, says Khademhosseini. The polymer building blocks are hydrophilic--they easily absorb water and resist interacting with oil. But they can't change their shape, so when Khademhosseini places them in an agitating bath of mineral oil, the blocks clump together in order to minimize their contact with the oil. The polymer blocks, now assembled into branches, cubes, and other shapes, are bonded together with another flash of light. The organization of the resulting structures can be controlled by varying the shape and size of the building blocks and the agitation speed. By repeating the process, Khademhosseini can build up larger and larger structures that resemble, for example, blood vessels running through tissue. And by combining building blocks of different shapes that fit together like a lock and key, Khademhosseini can build even more complex structures.

Berkeley Lab scientists have developed a nano-sized synthetic polymer bundle that can fold in half and trap a zinc molecule between its jaws, a first-of-its-kind feat that mimics how proteins conduct life's vital functions. The scientists' success in coaxing protein-like function from a synthetic polymer is an initial step toward developing nanostructures that combine the precision of proteins with the ruggedness of non-natural materials. Although very primitive by nature's standards, their polymer bundle could lead to highly accurate sensors capable of operating in harsh environments, or disease-targeting pharmaceuticals that last much longer than today's therapies.
