This study developed a probe Fe3O4-Cy5.5-trastuzumab with fluorescence and magnetic resonance imaging functions that can target breast cancer with high HER2 expression, aiming to provide a new theoretical method for the diagnosis of early breast cancer.
Methods:Fe3O4-Cy5.5-trastuzumab nanoparticles were combined with Fe3O4 for T2 imaging and Cy5.5 for near-infrared imaging, and coupled with trastuzumab for HER2 targeting. We characterized the nanoparticles used transmission electron microscopy, hydration particle size, Zeta potential, UV and fourier transform infrared spectroscopy, and examined its magnetism, fluorescence, and relaxation rate related properties...
