Physicists from the University of Georgia have developed a new way to create "natural motors" for tiny machines.
The researchers say the technique could lead to new methods of drug delivery, disease treatment and bioengineering, the university said in a release.
Their findings were published in the online edition of the American Chemical Society journal Nano Letters.
Physicists Yiping Zhao, Yuping He and Jinsong Wu said the catalytic nanomotors are naturally occurring power sources for nanometer-scale machines, which are powered by chemical reactions, the university said.
The new technique involves a simple modification of existing methods that allows for greater flexibility in designing desired nanomotor structures.
Zhao and team said the tiny machines could one day be the tools to open constricted or clogged blood vessels too small for conventional stents, or deliver drugs through the cell wall of an organism.

E. coli discovery could lead to new antibacterial target
Northeastern University scientists have discovered a new and unique DNA binding property of a protein in E. coli. Penny J. Beuning, Assistant Professor in the Department of Chemistry and Chemical Biology, spent the last two years researching double and single-stranded DNA binding of E. coli DNA polymerase III alpha protein and notes that her findings have potential for developing a new antibacterial target.
University of Pennsylvania engineers reveal what makes diamonds slippery at the nanoscale
They call diamonds "ice," and not just because they sparkle. Engineers and physicists have long studied diamond because even though the material is as hard as an ice ball to the head, diamond slips and slides with remarkably low friction, making it an ideal material or coating for seals, high performance tools and high-tech moving parts.
How cell's master transcribing machine achieves near perfection
One of the most critical processes in biology is the transcription of genetic information from DNA to messenger RNA (mRNA), which provides the blueprint for the proteins that form the machinery of life. Now, researchers have discovered new details of how the cell's major transcriptional machinery, RNA polymerase II (Pol II), functions with such exquisite precision. With almost unerring accuracy, Pol II can select the correct molecular puzzle piece, called a nucleosidetriphosphate (NTP), to add to the growing mRNA chain, although these puzzle pieces can be highly similar molecules.

Made-to-order isotopes hold promise on science's frontier
Designer labels have a lot of cachet -- a principle that’s equally true in fashion and physics. The future of nuclear physics is in designer isotopes -- the relatively new power scientists have to make specific rare isotopes to solve scientific problems and open doors to new technologies, according to Bradley Sherrill, a University Distinguished Professor of physics and associate director for research at the National Superconducting Cyclotron Laboratory at Michigan State University.
Warming up for Magnetic Resonance Imaging
Standard magnetic resonance imaging, MRI, is a superb diagnostic tool but one that suffers from low sensitivity, requiring patients to remain motionless for long periods of time inside noisy, claustrophobic machines. A promising new MRI method, much faster, more selective — able to distinguish even among specific target molecules — and many thousands of times more sensitive, has now been developed in the laboratory by researchers at the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley.
Computer game's high score could earn the Nobel Prize in medicine
