Microscopic gold tubes can both detect and destroy cancer cells

RATE THIS! +46

There's no doubt that doctors would prefer to treat cancer as soon as they spot it, and it looks like nanotechnology might give them that chance. Researchers at the University of Leeds have successfully tested gold nanotubes that are useful for both imaging and destroying cancer cells.

 

Since the tubes absorb near-infrared light frequencies, which both generate heat and render human skin transparent, you only need to zap them with lasers of varying brightness to achieve multiple ends. You can use a relatively low brightness to reveal tumors, while high brightness will heat the tubes enough to kill nearby tumorous cells. The shape also has room for drugs, so you can deliver medicine at the same time.

 
Scientists have only tried this approach in a mouse model of human cancer, so it'll be a long while before the technique is ready for your local hospital. However, it might be worth the wait. Besides saving time, the gold nanotubes both enter and leave your body with minimal fuss; you aren't as likely to grapple with side effects caused by methods like chemotherapy. If all goes well, you'd only need injections and laser blasts to deal with at least some life-threatening conditions.

Nanotechnology is proving that radically new treatments of cancer could be developed and provide alternative or new ways in both detection and treatment - yes, definitely worth a wait Reply

I don’t think you should use the dining plan on this unless you don’t want to pay out of pocket for this and &#&;202waste8#8221; the two table service credit meals for someplace else. Disney isn’t including tip but I’m not sure if tip is included at cinderella’s royal table. You can get a good deal at other places that don’t have a set price. So you can get more bang for your buck. Reply
