NanoIntegris Announces Sale of Metallic and Semiconducting Carbon Nanotubes

SKOKIE, Ill.--(Business Wire)--
NanoIntegris, an Illinois-based nanomaterials startup company,
announced today that it has begun selling samples of its metallic and
semiconducting single-walled carbon nanotubes (SWCNTs), which the
company has labeled IsoNanotubes, to customers worldwide.

Because of their unique electronic and optical properties, SWCNTs
have attracted considerable attention from researchers in the
electronics, energy, and biomedical industries over the past several
years. Most notably, SWCNTs can behave as either high-mobility
conductors or semiconductors, capable of outperforming traditional
materials like copper and silicon in applications such as integrated
circuits, flat-panel displays, and solar cells.

Limitations in SWCNT manufacturing, however, have long precluded
companies from utilizing SWCNTs for serious commercial R&D. "Current
SWCNT manufacturing techniques can only generate mixtures of nanotubes
that are electronically polydisperse, i.e. that contain both metallic
and semiconducting tubes," said Nathan Yoder, NanoIntegris's product
development manager. "But electronically polydisperse tubes are
unsuitable for many applications. The heterogeneity of commercially
available SWCNTs has consequently been a frustrating obstacle for
nanotechnology developers."

Despite the demand for electronically pure SWCNTs, attempts to
produce uniform metallic and semiconducting nanotubes have met with
limited success. "Researchers have been struggling to make SWCNTs of
uniform electronic type for over a decade," continued Dr. Yoder.
"Although various synthesis and processing techniques have been
developed which yield promising results on a laboratory scale, none of
these techniques has demonstrated the potential to produce
very-high-purity metallic and semiconducting tubes on a large,
commercial scale."

NanoIntegris's approach meets this scalability criterion. The
company has developed a novel centrifugation process for separating
commercially produced, electronically polydisperse SWCNTs by
electronic type. "Our process is effective and expandable," stated
NanoIntegris's executive vice president Dan Leven. "What is more, the
feedback we have received so far from customers regarding the
performance of our metallic and semiconducting SWCNTs has been
overwhelmingly positive. We are looking forward to working with
applications developers to incorporate our IsoNanotubes into future
commercial products."

NanoIntegris is a leading supplier of premium carbon nanotubes.
The company was spun out of the Hersam Research Group at Northwestern
University in early 2007. Its mission is to enable the
commercialization of new carbon nanotube applications by providing
researchers with materials of the type and purity they require.
