SWCNTs

Gold NPs Gold Nanorods

Figure 9.7 Schematic representation of non-covalent functionalisations onto gold
nanoparticles (NPs), single-walled carbon nanotubes (SWCNTs) and gold nanorods
(NRs). Figure modiied from Prencipe et al . 55 with permission. See also Colour Insert.

Figure 9.8 Blood circulation data of SWCNTs with different functionalisations in
BALB/c mice. Blood circulation curves of 1 - 3 coated nanotubes compared with DSPE-
branched-7kPEG coated nanotubes. The latter one was previously reported by the
same research group. Graph modiied from Prencipe et al . 55 with permission. See also
Colour Insert.

The enhanced quality of CNTs wrapped with PL-PEG complexes has
been conirmed through an investigation in the NIR region. 57 SWCNTs have
the intrinsic ability to display NIR photoluminescence, but irst they need
