A new technology, which creates a rainbow of optical colors with ultra-thin layers of silicon, has been recently demonstrated by a research group at the University of Alabama in Huntsville (UAH).
University of Washington scientists have built a new nanometer-sized laser using a semiconductor that's only three atoms thick. It could help open the door to next-generation computing that uses light, rather than electrons, to transfer information.
Biocompatible and biodegradable, cellulose materials are being studied for use in high-performance composites and optical films, and to deliver medicine in pills. But before a material can be commercialized, its impact on human health must be determined.
Using a mouse model of cancer, researchers at Washington University School of Medicine in St. Louis have devised a way to apply light-based therapy to deep tissues never before accessible. Instead of shining an outside light, they delivered light directly to tumor cells, along with a photosensitive source of free radicals that can be activated by the light to destroy cancer. And they accomplished this using materials already approved for use in cancer patients.
Scientists have captured the first real-time nanoscale images of lithium dendrite structures known to degrade lithium-ion batteries.
While the pattern for making a wearable fabric battery has already been laid out, it’s now time to select the threads that will turn a textile into an energy storage device. That process is being driven by Drexel University doctoral student Kristy Jost, who’s threaded her way into the forefront of research on conductive yarns.
Thanks to the work of an interdisciplinary team of researchers at the Dartmouth Center of Nanotechnology Excellence, funded by the National Institutes of Health, the next-generation magnetic nanoparticles (MNPs) may soon be treating deep-seated and difficult-to-reach tumors within the human body.
A new microscope at the Hard X-ray Nanoprobe at NSLS-II will ultimately deliver nanoscale resolution imaging for everything from proteins to fuel cell catalysts.
Newly developed tiny antennas, likened to spotlights on the nanoscale, offer the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer, according to the Australian scientists who created them. In the Journal of Applied Physics, they describe these and other envisioned applications for their nanocubes in "laboratories-on-a-chip."
Superconductor materials are prized for their ability to carry an electric current without resistance, a valuable trait crippled or lost when electrons swirl into tiny tornado-like formations called vortices. To keep supercurrents flowing at top speed, scientists have figured out how to constrain troublesome vortices by trapping them within extremely short, ultra-thin nanowires.
Researchers at McGill University have developed a new, low-cost method to build DNA nanotubes block by block – a breakthrough that could help pave the way for scaffolds made from DNA strands to be used in applications such as optical and electronic devices or smart drug-delivery systems.
By loading magnetic nanoparticles with drugs and dressing them in biochemical camouflage, Houston Methodist researchers say they can destroy blood clots 100 to 1,000 times faster than a commonly used clot-busting technique.
MIT chemical engineers have designed a new type of self-healing hydrogel that could be injected through a syringe. Such gels, which can carry one or two drugs at a time, could be useful for treating cancer, macular degeneration, or heart disease, among other diseases, the researchers say.
Researchers at the U.S. Department of Energy’s Argonne National Laboratory have revealed previously unobserved behaviors in nanrods that suggest new rules for the behavior of nanorod ensembles and new insights into how to increase heat-transfer efficiency in a nanoscale system.
Nanometer-sized “drones” that deliver a special type of healing molecule to fat deposits in arteries could become a new way to prevent heart attacks caused by atherosclerosis.
Microbiomes have been slow to yield their secrets. Two researchers explain how nanoscience might help speed up the process.
Researchers at the University of Maryland, Baltimore County (UMBC) have isolated a peptide, a type of biological molecule, which binds strongly to lithium manganese nickel oxide (LMNO), a material that can be used to make the cathode in high performance batteries. The peptide can latch onto nanosized particles of LMNO and connect them to conductive components of a battery electrode, improving the potential power and stability of the electrode.
A novel approach to growing nanowires promises a new means of control over their light-emitting and electronic properties. Berkeley Lab researchers demonstrated a new growth technique that uses specially engineered catalysts. These catalysts have given scientists more options than ever in turning the color of light-emitting nanowires.
Johns Hopkins researchers report they have used nanoparticles to successfully deliver a new therapy to cancer cells in the brains of rats, prolonging their lives.
