Image via Wikipedia A doctor who specializes in treating aneurysms has been searching for a way to prevent some patients–certain genotypes are more susceptible–from suffering strokes within days after initial treatments. Seems after the aneurysm‘s been addressed, the brain tends to become inflamed, which causes blood vessels to constrict and increases the likelihood of clots … Continue reading Nitric oxide may save lives post-aneurysm →

Nanomaterials have been in use for decades. But you never saw the term “nanoparticles” in such up-close-and-personal products as eyeliner. Manufacturers didn’t think at that point it was necessary to point out such an unusual ingredient. Today nanotechnology is increasingly used for making bio-materials–things that can be applied to or used in the human body. … Continue reading Nanotechnology good for synthetic blood →

A product that can help people with medical problems from controlling diabetes to growing hair to preserving transplant organs? Snake oil, anyone? Nope. A blue bandage made with synthetic nanoparticles promises just such wonders. Its secret? When you wet the bandage, the way the fibers degrade releases nitric oxide–a natural chemical that works wonders for … Continue reading Nanotech teams with nitric oxide to help diabetics, organ transplants →

Nano looks like it may provide a newly precise way of aiming only at cancer cells and avoiding inflammation, thus leaving healthy cells in their natural state. Nanoengineers Mine Tiny Diamonds For Drug Delivery. Fascinating to learn that these “diamonds,” which are structurally not unlike their namesake minerals, are welcomed by cells because they are … Continue reading Nanostructures like Diamonds can deliver cancer drugs precisely →

At an international conference in Cleveland, Ohio this week, nanoscientists from around the world are meeting with nano-lovers from industry and academia. One of the speakers during aerospace day technical sessions mentioned nano-geo-bio-chemistry–talk about your cross-functional sciences–being able to determine how a small item found in a cave affects the evolution of the earth. He … Continue reading Getting tinier and tinier–nano for optical lithography →

Two of England’s respected scientific societies feel there are too many unknowns and the toxic potential is great enough to warrant approving the sale of cosmetics laced with nanoparticles. The the U.S. FDA has a less restrictive policy. “Preliminary experiments in animals have found nanoparticles capable of moving into and damaging the lungs, brain and other … Continue reading Nano-spiked cosmetics on hold in England →
