Abstrakt: Background: Theranostic agents can combine photosensitizers and contrast agents into a single unit for photothermal therapy (PTT) and magnetic resonance imaging (MRI). The possibility of treating and diagnosing malignant cancers without any ionizing radiation could become an option. This study investigates the theranostic potential of Fe 3 O 4 nanoparticles (IONs) for the diagnosis and treatment of cancer by developing a single integrated nanoprobe.
Methods: Oleylamin-coated IONs (ION-Ol) were synthesized and surface of the IONs was modified using protoporphyrin (PP) and trastuzumab (TZ) to develop the TZ-conjugated SPION-porphyrin [ION-PP-TZ]. The structure, morphology, size, and cytotoxicity of all samples were investigated using Fourier-transform infrared spectroscopy (FT-IR), Transmission electron microscopy (TEM), X-ray powder diffraction (XRD), WST-1 assay, respectively. In addition to MRI and in vitro laser irradiation (808 nm, 200 mW) to determine the r 2 values and photothermal ablation.
Results: The sizes of monodispersed nanoparticles were measured in rang 5.74-7.17 nm. No cytotoxicity was observed after incubating MCF 7 cells under various Fe concentrations of nanoparticles and theranostic agents. The transverse relaxation time of the protoporphyrin conjugated to IONs (52.32 mM -1 s -1 ) exceeded that of ION-Ol and TZ-conjugated ION-PP. In addition, the in vitro photothermal ablation of ION-PP-TZ revealed a 74 % MCF 7 cell reduction after 10 min of at the highest Fe concentration (1.00 mg Fe/mL).
Conclusions: In summary, the water-soluble ION-PP-TZ is a promising bimodal agent for the diagnosis and treatment of human epidermal growth factor receptor 2-positive breast cancer cells using a T 2 MRI contrast agent and photothermal therapy.
