Drug-delivering nano "drones" to help prevent heart attacks

By - March 2, 2015 2 Pictures
Scientists have developed targeted, biodegradable nano "drones" to deliver anti-inflammatory drugs that heal and stabilize arterial plaque in mice. Their work could pave the way for more effective prevention of heart attack and stroke in humans caused by atherosclerosis, in which artery walls thicken and suffer reduced plasticity due to an accumulation of white blood cells.

Magnetic nanoparticles quickly bust blood clots to promise improved stroke prevention

By - February 23, 2015 1 Picture
Tissue plasminogen activator (tPA) is a drug commonly used by surgeons to bust open blood clots in a patient's bloodstream, but it does have its limitations. Once injected, there's no guarantee it will reach the site of the blood clot, and even then, having it arrive in the correct dosage can be tricky, with the risk of hemorrhage a very real possibility. Researchers have now found that using a new type of magnetic nanoparticle to deliver the drug offers a much more efficient journey to the site, promising to destroy blood clots 100 to 1,000 times faster and aid significantly in the prevention of heart attacks and strokes.

More human-friendly antibacterial coating made from gold

By - February 20, 2015 1 Picture
We've been hearing a lot about the antibacterial qualities of silver, with silver nanoparticles finding use in everything from water filters to food packaging. Unfortunately, there are also concerns about the toxicity of those particles, particularly when they enter our bodies. Now, however, Polish scientists have developed what they claim is a safer alternative – an antibacterial coating that kills microbes using gold. Read More

Gold nanotubes used to image and destroy cancer cells

By - February 16, 2015 1 Picture
For some time, the potential of gold nanoparticles as a diagnostics and imaging tool has been known to scientists, but new research suggests they could prove even more useful than previously thought. A team at the University of Leeds has discovered that shaping the particles in the form of nanotubes sees them take on a number of new properties, including the ability to be heated up to destroy cancer cells.

Nanobot micromotors deliver medical payload in living creature for the first time

By - January 21, 2015 1 Picture
Researchers working at the University of California, San Diego have claimed a world first in proving that artificial, microscopic machines can travel inside a a living creature and deliver their medicinal load without any detrimental effects. Using micro-motor powered nanobots propelled by gas bubbles made from a reaction with the contents of the stomach in which they were deposited, these miniature machines have been successfully deployed in the body of a live mouse.
