CC Biotech LLC, Rockville MD, developing advanced separations technologies for large molecules, is awarded an SBIR phase I grant from the National Science Foundation for the project ‘Spiral Countercurrent Chromatography for the Separation of Carbon Nanotubes’. The new technique has been applied for the first time to successfully purify single wall carbon nanotube species which are semi-conductors. The application will enable the processing of potent semi-conductors to be added to sensor circuits. The implications of this R&D have wide application to not only bio-sensor devices, but also in the preparation of nanotech molecules as therapeutic nanoparticles and conjugates for drug delivery.
