An international team of scientists is getting closer to perfecting molecule-sized motors that drill through the surface of cancer cells, killing them in an instant.
Researchers at Rice University, Durham (U.K.) University and North Carolina State University reported their success at activating the motors with precise two-photon excitation via near-infrared light. Unlike the ultraviolet light they first used to drive the motors, the new technique does not damage adjacent, healthy cells.
The research led by chemists James Tour of Rice, Robert Pal of Durham and Gufeng Wang of North Carolina may be best applied to skin, oral and gastrointestinal cancer cells that can be reached for treatment with a laser.
In a 2017 Nature paper, the same team reported the development of molecular motors enhanced with small proteins that target specific cancer cells. Once in place and activated with light, the paddlelike motors spin up to 3 million times a second, allowing the molecules to drill through the cells' protective membranes and killing them in minutes.
Since then, researchers have worked on a way to eliminate the use of damaging ultraviolet light. In two-photon absorption, a phenomenon predicted in 1931 and confirmed 30 years later with the advent of lasers, the motors absorb photons in two frequencies and move to a higher energy state, triggering the paddles.

A drill, yeah that’s one way to get rid of cancer.
I wonder how they work on kneecaps?
I’ll believe that when I can get a knockoff at Harbor Freight.
Check out a few videos on James Tour of Rice. Tour is one of the world’s leading synthetic organic chemist, specializing in nanotechnology. He’s also a very devout Christian.
There are some good videos on him if you search for them. I sure wish we had more like him.
Here is a little more information on him:

Every little bit helps.

Here is a short video of Dr. James Tour. Very impressive.

Really great.
Wonderful that they keep working on different cancer treatments.
Fenbendazole Shows incredible promise for most cancers. No report on leukemia It’s cheap and from testimonials aeradicates cancers in 6 months...and all you need is to buy canine dewormer

We work on them just fine.
Thanks fieldmarshaldj.
