We aren't even close to having any sort of a handle on genetic endineering technology, and this nano-tech is potentially waay more harmful. This stuff can penetrate the blood/brain barrier. just sayin.

You can't see it, but it makes sunscreen clear, tennis rackets light and khaki pants stain repellent. And someday, it might help cure cancer.
It's called nanotechnology.
Dealing with particles that are 1/100,000th as wide as a human hair, nanotechnology is one of today's most promising avenues of research in medicine, science and manufacturing.
But experts say it could also be one of the most perilous, dealing as it does with particles so minuscule they can be ingested into the lungs or seep into the bloodstream through the skin without detection.
"The biggest worry is that you're creating materials that behave in different ways because they are so small. It seems very foolish to cross our fingers and hope for the best -- without doing tests," said Andrew Maynard, science adviser to the Project on Emerging Technologies, an initiative by the Woodrow Wilson International Center for Scholars in Washington.
The technology has also progressed faster than federal regulatory agencies can issue guidelines, he said. The result is many consumer products with nano-particles that have not undergone rigorous testing. The greatest concerns are products with nano-particles that might be absorbed by the body.
"We don't know what is safe and what is harmful," Maynard said, yet new nano-products appear on store shelves every day.
