Abstract
Quantum dots (QDs) and Fe3 O4 nanoparticles were conjugated onto the surfaces of carbon nanotubes (CNTs) for medical diagnosis and treatment. The nanoassembly was designed to meet the specific needs in cancer in vivo imaging and simultaneous treatment. The key functionalities needed for clinical applications were integrated, including CNT surface functionalization for attachment of biological molecules in targeting, drug storage capabilities, fluorescent emissions near the infrared range, and magnetic hyperthermia. CNT-QD- Fe3 O4 developed exhibited a strong fluorescence near the infrared region for noninvasive optical in vivo imaging. Magnetization measurements showed nearly reversible hysteresis curves from CNT-QD- Fe3 O4 nanoassembly. Fe3 O 4 conjugated CNT was found to experience hyperthermia heating under alternating electromagnetic field. © 2009 American Institute of Physics.
