As an associate of the Particles, Tubes, and Colloids project at NIST we are working on the extraction and purification of single wall carbon nanotubes (SWCNTs). Specifically, we use DNA modulated PEG/Salt aqueous two-phase (ATP) systems to extract single chirality SWCNTs. These high purty DNA-SWCNTs have a large fluorescence response in the presence of serotonin, cholesterol, and dopamine including solvatochromic shifts and changes in intensity. This makes DNA-SWCNTs ideal optical reporters for in-situ imaging and sensing. Additionally metallic SWCNTs are useful in electronics for single molecule sensing.
