A novel multifunctional nano-probe is developed on page 4114 by Y. Hou, L. Zhao, F. Sheng, and co-workers based on Fe5C2 nanoparticles with carbon layer. The probe exhibits high magnetization and near infrared absorption, which can be applied in magnetic resonance imaging, photoacoustic tomography, and photothermal therapy. It shows a high affinity to tumors, and can ablate them when exposed to light, highlighting their potential as a targeted probe for cancer theranostics.
