The latest application of nano-technology is to understand the DNA damaging agents, by putting sensors right inside the cells As a bonus, this method can also be used to deliver the drugs inside the cells. This is a boon to detect the specific toxins which cause cancer. Tying bells to sheep or cows to find out their presence in dense fog in the mountains is a well-known practice. To find a black cat in a dark room, instead of tying a bell, a small torch is still better. This is the radioactive tracer technique. What Dr. Michael Strano of MIT has been able to achieve is to detect the nano of nano particles, the DNA by putting fluorescent sensors right inside. Nano carbon molecules, thousands of times smaller than a human hair are now used by many research groups. Strano's team carefully coated specially shaped nano carbon tubes with DNA more...
