Researchers have, for the first time, changed the orientation of a very large number of electron spins collectively at room temperature by pure electrical means, a feat that eventually could make devices that use spintronics more readily available for everyday uses.
ISO has published a new technical report, ISO/TR 11360:2010, Nanotechnologies - Methodology for the classification and categorization of nanomaterials, offering a comprehensive, globally harmonized methodology for classifying nanomaterials.
Harnessing darkness for practical use, researchers at the National Institute of Standards and Technology (NIST) have developed a laser power detector coated with the world's darkest material - a forest of carbon nanotubes that reflects almost no light across the visible and part of the infrared spectrum.
Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible.
A cluster of carbon nanotubes coated with a thin layer of protein-recognizing polymer form a biosensor capable of using electrochemical signals to detect minute amounts of proteins. With further development, this biosensor could provide a crucial new diagnostic tool for the detection of cancer and other illnesses.
In cancer research, nanotechnology holds great promise for the development of targeted, localized delivery of anticancer drugs, in which only cancer cells are affected. By carrying out comprehensive studies on mice with human tumors, scientists at the University of California, Los Angeles, have obtained results that move the research one step closer to this goal.
