Fluor-PEG functionalized SWNTs. a) Schematic showing SWNT and Fluor-PEG (1). b) Atomic force microscopy image of Fluor-PEG/SWNTs deposited on substrate. c) Photo of Fluor-PEG/SWNT in water (left, yellow-green color due to SWNT bound Fluor), after heating at 70 °C for 2 days (center), and in cell culture medium supplemented with 10% serum (right, red color due to cell medium). Unbound Fluor-PEG was dialyzed in the starting solution.
