'Star Wars'-like light syringe could target cancer

OK, the whole Star Wars thing? A little misleading.

Basically, the Herald Sun is reporting on a technology that involves firing a laser beam accurate enough to puncture a hole in an individual cell. Sounds more like The Authority--or any other Mark Millar-written comic--than Star Wars to me.

Anyway, Professor Kishan Dholakia and Dr. Frank Gunn-Moore--both of the University of St. Andrews in Scotland--say the "light saber" could be used routinely on cancer patients within the next five years.

The method would allow chemotherapy drugs to be pumped directly into cancer cells. The researchers believe hard-to-reach cancers such as that of the pancreas would especially benefit.

The researchers have managed to mount the light syringe on an optical fiber the width of a human hair. The next step is to develop it for use on endoscopes, the tubes used by surgeons to pass miniature cameras through the body.

"You could think of these as tiny light sabers like they had in Star Wars inside your body," Gunn-Moore said.

"We can use lasers to punch tiny holes exactly where we want them," he continued. "We can produce a rod of light--sometimes described as a sword--that can even go around objects. It really does sound like science fiction."

So not really "Star Warsian," exactly, but mentioning Star Wars has surely led to better coverage of the team's research. But hey, if more coverage leads to more funding, then more power to them.

Scientists at the University of St Andrews in Scotland have developed a novel form of syringe, formed solely from light, that they hope will deliver highly targeted chemotherapy drugs.

You don't need chemicals when you can kill cancer cells directly with laser light. Microvision has a tiny pivoting mirror for laser projection and endoscopic camera applications, but the same technology, if shrunken down, could be used to direct more powerful lasers to kill cancer cells. You would only need a small incision to get the mirror near or inside the tumor.

its interesting. though, if they can do this to cancer cells, what about hiv?

HIV is spread throughout the body. A tumor is, if you get it before the cancer metastasizes, in one localized region.
