Cnano Technology, a developer of carbon nanotubes, raised $6 million. CMEA Ventures and Pangaea Ventures led the round, joined by WI Harper.

Cnano, which maintains offices in Menlo Park, Calif., and a manufacturing facility in China, aims to improve the quality and efficiency of nanotube manufacture. Nanotubes are tiny tubes, often only a few atoms wide, that are formed out of a single-atom-thick carbon mesh-like structure. The tubes exhibit tremendous tensile strength and have other unusual properties, such as conducting heat and electricity in a controllable fashion.

From the company’s release:

Cnano has pioneered a novel hybrid technology that results in significantly reduced manufacturing costs compared to any other carbon nanotube production methods to date. “Since the discovery of carbon nanotubes, the applications have been limited due to high costs. With our patented, mass production technology, Cnano is strategically positioned to provide high quality nanotube products at good prices for our customers,” noted Xindi Wu, Cnano president and CEO.

Nanotubes, which can also be manufactured in a “nested” form known as multiple-walled nanotubes, may have important applications in biotechnology and sensitive diagnostics. The tubes may also be useful in developing super-strong fibers and other materials, and might be important as a way of helping chipmakers keep up with Moore’s Law.
