 | A group of scientists has succeeded in creating the first transistor made from a single molecule. The team, which includes researchers from Yale University and the Gwangju Institute of Science and Technology in South Korea, showed that a benzene molecule attached to gold contacts could behave just like a silicon transistor. ...> Full Article |
 | A team led by Yale University researchers has used nanosensors to measure cancer biomarkers in whole blood for the first time. Their findings could dramatically simplify the way physicians test for biomarkers of cancer and other diseases. ...> Full Article |
Tiny nanoprobes have shown to be effective in delivering cancer drugs more directly to tumor cells -- mitigating the damage to nearby healthy cells -- and Purdue University research has shown that the nanoprobes are getting the drugs to right cellular compartments.

 | A team of researchers from the University of Vigo, Rutgers University in the United States and Imperial College London, in the United Kingdom, has developed "laser spinning," a novel method of producing glass nanofibres with materials. They have been able to manufacture bioglass nanofibres, the bioactive glass used in regenerating bone, for the first time. ...> Full Article |
A team of University of Illinois at Chicago chemists, lead by assistant professor Petr Král report the ability to bend and reshape graphene, opening up the possibility of forming new and novel devices in the nanoscale. They use an everyday household ingredient to perform the work -- a droplet of water.

 | Scientists at Georgia Tech have developed a nanolithographic technique that can produce high-resolution patterns of at least three different chemicals on a single chip at writing speeds of up to one millimeter per second. The nanopatterns can be designed with any shape and are stable enough to be stored for weeks and used elsewhere. ...> Full Article |
A dozen laboratories in the Texas Medical Center, including four from Rice University, have won a $3 million Grand Opportunity grant from the National Institutes of Health to conduct a systematic survey of how different sizes and types of nanoparticles behave inside living cells. The two-year project, which is funded by the American Recovery and Reinvestment Act, could speed the development of nanomedicine.

 | "Yes, we're going to make skis. No, it's not really Ski Building 101," said Kam K. Leang, the faculty member and principal investigator for a project to further integrate nanotechnology into the undergraduate curriculum at the University. Leang and his colleagues aim to prepare 21st century mechanical engineers at the University to meet the emerging challenges of nanotechnology using a top-down approach where the first important step is to excite them about the technology. ...> Full Article |
Scientists at the US Department of Energy's Argonne National Laboratory are developing a way to control the Casimir force, a quantum mechanical force, which attracts objects when they are only hundred nanometers apart.

Currently chip manufacturers are facing great challenges in miniaturizing transistors, a semiconductor device commonly used to amplify or switch electronic signals. A recent study, published in the November 27 issue of Science, details how a team of researchers from UCLA, Purdue and IBM have successfully grown semiconducting nanowires made of silicon-germanium that could lead to a new generation of smaller, faster, and more powerful electronics many hope for in the industry.

 | Nanoscale machines expected to have wide application in industry, energy, medicine and other fields may someday operate far more efficiently thanks to important theoretical discoveries concerning the manipulation of famous Casimir forces that took place at the US Department of Energy's Ames Laboratory. ...> Full Article |
 | Researchers have used lasers to create the first practical macroscopic yarns from boron nitride fibers, opening the door for an array of applications, from radiation-shielded spacecraft to stronger body armor, according to a just-published study. ...> Full Article |
A University of Pittsburgh team overcame a major hurdle plaguing the development of nanomaterials such as those that could lead to more efficient catalysts used to produce hydrogen and render car exhaust less toxic. The researchers reported Nov. 29 in Nature Materials the first demonstration of high-temperature stability in metallic nanoparticles, the vaunted next-generation materials hampered by a vulnerability to extreme heat.
