Paper Abstract

Here we present that single-walled carbon nanotubes(SWNT) coated with poly(ethylene glycol) (PEG) can be used as a contrast agent for photoacoustic molecular imaging. In vitro and in vivo experiments results show a good enhancement of the optical absorption by SWNT in photoacoustic imaging. The experimental results also show that a high contrast and a high efficient targeting of integrin αvβ3 positive U87 human glioblastoma tumours in mice could be achieved. This study suggests that photoacoustic molecular imaging with antibody functionalized SWNTs has the potential to be an effective early tumor diagnoses method.
