Search results for nanoparticles

Would you buy a cloudy white wine? Probably not, which is why vintners go to great lengths to clarify their product. Soon, they could do so more efficiently than ever, using newly created nanoparticles.Continue ReadingCategory: ScienceTags: University of South Australia, Nanoparticles, Wine
Viruses are getting a pretty bad rap lately, but they’re not always our enemy. In a new study led by the University of Verona, researchers have used plant viruses to make new nanoparticles that show promise in mice for treating autoimmune diseases like type 1 diabetes and rheumatoid arthritis.Continue ReadingCategory: Medical, ScienceTags: Plants, Virus, John Innes Centre, Diabetes, Arthritis, Rh
Not all maple syrups are created equal. There are actually over 60 taste categories that syrups fall into, as determined by human taste-testers. Soon, though, a solution containing gold nanoparticles could save those people some work.Continue ReadingCategory: ScienceTags: University of Montreal, Food technology, Taste, Gold, Nanoparticles
Brain cancers are particularly insidious for many reasons, not least of which is that the brain’s own defense mechanism often prevents treatment. But a new experimental technique has shown success in mice, with carbon nanoparticles able to sneak through the blood-brain barrier and deliver drugs directly to tumors.Continue ReadingCategory: Medical, ScienceTags: Cancer, Brain cancer, Brain, Blood-b
The best way to fight off cancer might be to strengthen the body’s immune system to help identify and kill tumors. This is known as immunotherapy. Now researchers have developed artificial nanoparticles that should be cheaper and easier to produce.
Causing the death of cancer cells while leaving healthy ones in tact is central to the goal of safer, more effective forms of treatment for the disease, and scientists have now come up with one that leans heavily a common household item – salt.
A new type of copper-based nanoparticle has shown effectiveness in killing off tumor cells in mice. But by combining it with immunotherapy scientists say it produced long-lasting effects, quickly killing off any cancer cells that dared to return.
One of the main reasons cancer can be so difficult to beat is because of its ability to spread through the body, even after the primary tumor has been surgically removed. But now researchers from Vanderbilt University have developed a new technique that uses nanoparticles to enhance immune cells, helping them hunt down cancer cells migrating through the bloodstream...

When a spinal cord injury occurs, sometimes it's the body's own immune system that causes the subsequent paralysis. In the not-too-distant future, however, it's possible that an injection of nanoparticles at the injury site may be able to reign in the well-meaning but destructive immune cells... Continue Reading Injected after accidents, nanoparticles could prevent paralysis Category: Med
Scientists are exploring all kinds of ways to improve cancer treatments, with some methods more tried-and-true and others at the experimental end of the spectrum. Using magnetism to heat up nanoparticles inside a tumor to destroy nearby cancer cells certainly falls among the latter, but scientists are now reporting an exciting advance in this area with some promising early results on mice.
