A new study predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode information.
Scientists a new kind of multi-tasking stent that could minimize the risks associated with a procedure to unblock clogged arteries. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job.
The Nanotechnology Applications and Career Knowledge Network initiated the development of two new standards: Guide for Workforce Education in Nanotechnology Health and Safety, and Practice for Workforce Education in Nanotechnology Characterization.
Precious metals like silver and gold have biomedical properties that have been used for centuries, but how do these materials effectively combat the likes of cancer and bacteria without contaminating the patient and the environment?
Superconductivity is a rare physical state in which matter is able to conduct electricity without any resistance. It can only be found in certain materials, and even then it can only be achieved under controlled conditions of low temperatures and high pressures. New research hones in on the structural changes underlying superconductivity in iron arsenide compounds - those containing iron and arsenic.
Scientists around the world are using the programmability of DNA to assemble complex nanometer-scale structures. Until now, however, production of these artificial structures has been limited to water-based environments, because DNA naturally functions inside the watery environment of living cells. Researchers have now shown that they can assemble DNA nanostructures in a solvent containing no water.
