Engineers are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers have created a new 'smart bandage' that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes - and while recovery is still possible.
Scientists have developed a highly efficient oxygen-producing electrode for splitting water that has the potential to be scaled up for industrial production of the clean energy fuel, hydrogen. The new technology is based on an inexpensive, specially coated foam material that lets the bubbles of oxygen escape quickly.
Graphene oxide, a water-soluble derivative of graphene with many functional groups on the surface, is one of the best candidates for fabricating bioinspired layered materials, because functional surface groups enable interface designs that can improve the interfacial strength in composites.
TAPPI announced that Dr. Theodora Retsina, CEO of American Process, Inc. (API) and Dr. Maria Delorio, Executive Director of the National Institute for Nanotechnology (NINT) and Professor of Physics and Assistant Vice President of Research at the University of Alberta, will be keynote speakers at the 2015 International Conference on Nanotechnology for Renewable Nanomaterials, in Atlanta, Georgia, June 22-25.
A step in understanding how microbes infect target cells. The findings have potential long-term applications for developing new antibiotics against salmonella and certain other disease-causing bacteria, for designing bacteria that could inject cancer cells with chemotherapy drugs, and for helping people how to design machines at the nanoscopic or molecular scale.
Researchers have shown that spherical nucleic acids (SNAs) can be used as potent drugs to effectively train the immune system to fight disease, by either boosting or dampening the immune response. The initial treatment triggers a cell-specific immune response all over the body.
Today, the PETA International Science Consortium put out a request for proposals to identify facilities that can develop an in vitro test that, when used in an integrated approach, has the potential to replace the current test conducted on animals to assess the inhalation toxicity of nanomaterials.
Researchers have shown that the use of nanoparticles to carry antibiotics across biological barriers can be effective in treating lung infections. Doing so allows better delivery of the drug to the site of infection, and hence prevents the development of antibiotic resistance which may be caused by too large and continued doses of antibiotic.
In the eyes of physicists, magnetic molecules can be considered as nanoscale magnets. Remotely controlling the direction in which they rotate, like spinning tops, may intuitively be difficult to achieve. However, physicists have just demonstrated that it is theoretically possible to do so.
