A new microspectrometer architecture that uses compact disc-shaped resonators could address the challenges of integrated lab-on-chip sensing systems that now require a large off-chip spectrometer to achieve high resolution.
Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, has assembled a new collection of its nanotechnology-focused web tutorials and seminars in a convenient CD format.
Semiconductor Research Corporation (SRC), the world's leading university-research consortium for semiconductors and related technologies, and researchers from SEMATECH and The University of Texas at Dallas are the first to demonstrate that specific potentially hazardous organic contaminants present in a type of single-walled carbon nanotubes can be easily removed.
The project will create nano-enabled solutions for introducing and exploiting RFID (Radio Frequency Identification) technology in Russia's retail industry. If successful in its development work, the project will establish a company-integrator to introduce RFID technology to domestic retail trade.
U.S. Senator Kirsten Gillibrand, member of the Armed Services Committee, secured approval for an increased focus on nanotechnology research by the Defense Department, including a study to determine the need for a center for nanotechnology.
State-of-the-art equipment for generating composite semiconductor structures has been launched at the Faculty of Physics, University of Warsaw. First micropillars, micrometer-sized columns made up of many carefully selected layers of thickness of the order of nanometres, have been generated in the laboratory in Warsaw. They will be used, among others, to build efficient yellow light lasers. The new equipment also opens up unique educational possibilities for students in the field of nanotechnology engineering.
Researchers at Delft University of Technology and the University of Basel have established a biomimetic nanopore that provides a unique test and measurement platform for the way that proteins move into a cell's nucleus.
Quantum dots are particularly promising for biological imaging, having size-tunable light emission and excellent photostability. The development of such clinical applications, however, hinges on understanding how such nanoparticles interact with and penetrate living cells. A research team led by Hongda Wang from the Chinese Academy of Sciences has now developed a method to measure these interaction forces using atomic force microscopy.
Hollow nanotubes with walls just a few atoms thick are increasingly being used to monitor biological processes in individual cells. Such nanotubes can be loaded with fluorescent molecules that respond to certain biochemicals or a change in temperature or pH with a measurable change in fluorescence. Most of the biological probes developed so far rely on carbon nanotubes. Now, a research team from Japan has now produced a probe using nanotubes made of boron and nitrogen atoms.
Two Virginia Tech research groups have combined forces to devise a way to measure Nafion's internal structure and, in the process, have discovered how to manipulate this structure to enhance the material's applications.
Have you ever wondered what happens to sunscreen after it swirls down the drain with your soap? Probably not, but it is a question that makes Prof. Chin-Pao Huang curious. Sunscreen contains titanium dioxide, an engineered nanoparticle (ENP) that improves the product's performance, reducing your sunburn risk while outdoors.
