We talk a lot about the wonders of nanotechnology here at Gizmag. After all it’s easy to get caught up in the excitement surround the technology when it promises to revolutionize practically every area of human endeavor. Among its long list of anticipated benefits are new medical treatments; stronger, lighter materials; improved energy production, storage and transmission; and more effective pollution monitoring and prevention, just to name a few. But nanotechnology is not just something set to come about in some far off future – it is happening now. In fact, the odds are there is a product either containing, or made using nanoparticles sitting in your house right now. But the big question is, are they safe? Read More
Nanosized drug delivery systems take a leap forward
19:03 November 3, 2009 PST
Blood vessels that supply tumors are more porous than normal vessels, makes nanoscale drug delivery systems a particularly attractive prospect. If properly engineered, nanoparticles can in fact get inside a tumor, targeting it precisely and allowing much higher drug dosages as they reduce side effects to a minimum. Two recent studies featured in the latest issue of the journal Nature Materials specifically address these issues and give us promising leads in the fight against cancer. Read More
Sugar-coating nanoparticles to tempt cancer cells brings dual benefits

Researchers believe nanoparticles hold the promise of battling cancer without the damaging side effects of chemotherapy or radiation treatment. They have discovered that coating minuscule balls of iron oxide with sugar molecules not only makes them particularly attractive to resource-hungry cancer cells, it also makes them more effective by allowing them to get close to each other, but not too close to render treatment ineffective.

Painting brain tumors with nanoparticles may help defeat cancer
22:52 August 12, 2009 PDT
Nanotechnology is preoccupying science to the point where it's starting to seem unremarkable. But a group of researchers from the University of Washington has released findings that could profoundly improve the chances of surviving brain cancer. The team has developed a fluorescent nanoparticle that is capable of penetrating – for the first time – the blood-brain barrier without damaging it. The fluoro nanoparticle targets tumors using a derivative of scorpion venom and enables precise imaging of the size and location of cancerous growths. When the particles meet the tumor, they light up like Christmas. Read More
