Production and characterization of PEG-SWCNTs. A. PEG-SWCNT were fabricated by the adsorption onto pristine SWCNTs of phospholipids modified with PEG chains carrying an amino group at their end. PEG-SWCNT-750 were obtained by capping the PEG chain terminal amino groups on PEG-SWCNTs with NIR-emitting fluorochrome (Seta750). B. AAC-mode AFM image of PEG-SWCNTs deposited on freshly cleaved mica sample (scan size 2.5 × 2.5 μm). C. PEG-SWCNT length distribution (N = 256).
