New artificial muscles made from nanotech yarns and infused with paraffin wax can lift more than 100,000 times their own weight and generate 85 times more mechanical power than the same size natural muscle, according to scientists at The University of Texas at Dallas and their international team from Australia, China, South Korea, Canada and Brazil.
Detecting whether a patient will have acute kidney injury could become as simple as dipping a paper test strip printed with gold nanorods into a urine sample, a team of Washington University in St. Louis researchers has found.
To detect the toxicity of engineered nanomaterials, such as carbon nanotubes, on living cells, researchers have developed a "nanocanary", the modern-day, high-tech equivalent of the canary in a coal mine that warned miners of dangerous buildups of toxic gases in the mine shaft.
A novel push coating technique that uses an original silicone rubber stamp having a trilayer structure has been developed. The technique enables highly efficient use of materials, improvement in thin-film crystallinity, and high resolution patterning. The findings should considerably accelerate the research and development of flexible electronic devices.
Researchers from the University of Southern California and the National Institute of Standards and Technology have demonstrated a technique for growing virtually pure samples of single-wall carbon nanotubes with identical structures, a process they liken to "cloning" the nanotubes. If it can be suitably scaled up, their approach could solve an important materials problem in nanoelectronics: producing carbon nanotubes of a specific structure to order.
A collaboration led by researchers from the NIST Center for Nanoscale Science and Technology has shown for the first time that charge carriers in graphene continue to behave as massless particles, like photons, over wider ranges of both density and energy than previously measured or modeled.
Researchers at the National Institute of Standards and Technology (NIST) have provided evidence in the laboratory that single-wall carbon nanotubes (SWCNTs) may help protect DNA molecules from damage by oxidation.
Sometimes simplicity is best. Two Northwestern University researchers have discovered a remarkably easy way to make nanofluidic devices: using paper and scissors. And they can cut a device into any shape and size they want, adding to the method's versatility.
One of the key challenges has been the reliability of the nanometer-scale tips, especially with performing nano-writing on hard, semiconductor surfaces. Now, researchers at the University of Illinois, University of Pennsylvania, and Advanced Diamond Technologies Inc., have created a new type of nano-tip for thermal processing, which is made entirely out of diamond.
There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.
