Targeted Fe-filled carbon nanotube as a multifunctional contrast agent for thermoacoustic and magnetic resonance imaging of tumor in living mice

As the carbon nanotubes (CNTs) are filled with Fe nanoparticles, the microwave absorption of CNTs will have a significantly improvement. In the thermoacoustic imaging of tumor, the use of these hybrid particles can remarkably improve the contrast of images and increase the sensitivity of tumor detection.267
