Emeryville's Nanomix grows sensors and H2 storage: "There are a couple of different ways to make nanotubes, but Nanomix grows billions of them at a time on gold foil, producing what researchers there call "nanoturf." .. Scientists can customize nanotubes to react to different chemicals by coating them with metal atoms or winding around them polymers that boost the response to a given chemical. .. The change would be detected by attaching the nanotube to a regular microchip by a tiny metal wire, itself a few nanometers thick. "We think we've created an architecture that can sense just about every chemical known to man out of a single platform," [CEO] Janac says. ..

[Example:] an oil refinery that needs to detect hydrocarbon leaks. Today such a refinery would be equipped with several dozen conventional chemical sensors that cost about $3,000 apiece. But nano-sensors could cost less than $50 each, allowing a refinery to scatter thousands of them around its facility, providing better coverage and a better early warning system for the same or less money. If they can be accurate and cheap, nano-sensors could easily find themselves used more widely in other industries and even in household products. " Nanosys uses molecular computer simulations extensively.
