Abstract :
Magnetic resonance imaging (MRI) plays an essential role in molecular imaging by delivering the
contrast agent into targeted cancer cells. The aim of this study was to evaluate the C595 monoclonal antibodyconjugated
superparamagnetic iron oxide nanoparticles (SPIONs-C595) for the detection of breast cancer cell
(MCF-7). Methods: The conjugation of monoclonal antibody and nanoparticles was confirmed using X-ray
diffraction, transmission electron microscopy, and photon correlation spectroscopy. The selectivity of the
nanoprobe for breast cancer cells (MCF-7) was obtained by Prussian blue, atomic emission spectroscopy, and
MRI relaxometry. Results: The in vitro MRI showed that T2 relaxation time will be reduced 76% when using T2-
weighed magnetic resonance images compared to the control group (untreated cells) at the dose of 200 μg
Fe/ml, as the optimum dose. In addition, the results showed the high uptake of nanoprobe into MCF-7
cancer cells. Conclusion: The SPIONs-C595 nanoprobe has potential for the detection of specific breast cancer.
