Located in Riverside, California, Carbon Solutions, Inc. (CSI) was established in 1998 with the goal of manufacturing single-walled carbon nanotubes (SWNTs), in bulk quantities. In spite of its relatively short history the company has become one of the leading nanotechnology companies due to its reputation for producing high quality chemically processed carbon nanotube materials for commercial sale. CSI is the acknowledged leader in the development of purity evaluation techniques and was the first to develop quality control and quality assurance criteria for industrial sales of carbon nanotubes. The company is able to produce carbon nanotubes that are suitable for virtually any application by virtue of its ability to chemically process the SWNTs so as to introduce the necessary chemical functionality for compatibility with common industrial processes. The company currently has strong business relationships with leading companies interested in the development of carbon nanotube-based sensors, flexible electronics, transparent conductors, infrared and visible photodetectors.
