Combining Magnetic Resonance Imaging with Photothermal Therapy of CuS@BSA Nanoparticles for Cancer Theranostics
2018
The treatment of tumors has been a wide concern by a large number of scientific researchers. Combining magnetic resonance imaging (MRI) with photothermal therapy (PTT) enables cancer theranostics to be more efficient and accurate. Herein, we synthesized CuS@BSA nanoparticles with an average grain diameter of about 16.5 nm through a facile one-pot eco-friendly and user-friendly strategy and it was found to have strong near-infrared absorption property and magnetic resonance imaging ability so that it can be utilized as a multifunctional agent for cancer theranostic. The in vitro toxicity study showed that CuS@BSA nanoparticles with low toxicity could kill cancer cells with the 980 nm NIR laser effectively. Furthermore, they exhibit a certain value of relaxivity (r1 = 0.26 mM–1·s–1) compared to that of clinically widely used reagent Magnevist (r1 = 3.13 mM–1·s–1). The resulting product of CuS@BSA nanoparticles with their magnetic resonance imaging (MRI) and photothermal therapeutic capabilities could repres...
