How are we on carbon nanotubes these days? Is that a fizzler? I see a 15 year old kid has invented a cancer detection test which uses nanotubes that is:

168 times faster than what is currently available.
26,000 times less expensive. That’s not a typo.
And it’s potentially almost 100% accurate.

"Jack recognized that mesothelin is a key market to certain cancers. To create his test, Jack mixed human mesothelin-specific antibodies with carbon nanotubes and coated strips of ordinary filter paper."
