In 2006 researchers established that dogs could detect cancer by sniffing the exhaled breath of cancer patients. Now, using nanoscale arrays of detectors, two groups of investigators have shown that a compact mechanical device also can sniff out lung cancer in humans...The key development in Dr. Haick’s team’s work demonstrated that the electrical resistance of carbon nanotubes coated with nonpolymeric organic layers changes substantially when nonpolar organic molecules, such as those present in a breath, pass over the nanotubes.
I thought everyone would like to read about this. It's a little old, but the technology is still pretty cool.
This is really going to help lower cancer death rates. The biggest challenge with cancer is early detection. The earlier you detect the cancer, the better your chances are of beating it. If nanosensors could "smell" cancer, it would allow us to detect cancer before you even felt the symptoms like pain, swelling, etc!
I watch news a year ago about sensor. It has something to do with bionic parts on the body. The said man can communicate with computers.
I think that it is related to this one.
I want to become a bionic man with super strength and other bionic powers.
No not really. They are proposing to use nanotechnology to detect cancer cells. This would be a breakthrough, because the nanoprobes could detect cancer far in advance of the cancer reaching a critical point.
