In this paper, the luminescent complex Eu(3-thenoyltrifluoroacetonate) 3 was integrated with Fe 3 O 4 and gold (Au) nanoparticles to form a multifunctional nanocomposite, Fe 3 O 4 /Au/Eu(TTA) 3 (FOASET NC), for dual magnetic-photothermal therapy and biomedical imaging. Upon functionalization with amine-NH 2 , the FOASET NC exhibits a small size of 60-70 nm and strong, sharp emission at λ max = 614 nm, enhanced by surface plasmon resonance (SPR) of Au nanoparticles that provided an effective label for HT29 colorectal cancer cells by fluorescence microscopy imaging. In addition, a hyperthermia temperature (42-46 °C) was completely achieved by using these FOASET NCs in an aqueous solution with three heating modes for (i) Magnetic therapy (MT), (ii) Photothermal therapy (PT), and (iii) Dual magnetic-photothermal therapy (MPT). The heating efficiency was improved in the dual magnetic-photothermal heating mode. |
