We demonstrate polyethylene glycol coated single-walled carbon nanotubes (CNTs) as contrast agents for both photothermal optical coherence tomography (OCT) and magnetic resonance imaging. Photothermal OCT was accomplished with a spectral domain OCT system with an amplitude modulated 750 nm pump beam using 10 mW of power, and T2 MR imaging was achieved with a 4.7 T animal system. Photothermal OCT and T2 MR imaging achieved sensitivities of nM concentrations to CNTs dispersed in amine terminated polyethylene glycol, thus establishing the potential for dual-modality molecular imaging with CNTs.
