Abstract:
Tumor specific superparamagnetic nanoparticle conjugates are currently being developed as targeting-contrast agents for magnetic resonance imaging (MRI). The application of such “smart” molecular imaging probes will have a significant clinical impact as a non-invasive method of cancer detection and diagnosis. In this study, we examine the vitamin folic acid (FA) as a targeting agent for the delivery of superparamagnetic nanoparticles to specific tumor cells in vitro. Results from this study suggest that the synthesized FA-superparamagnetic nanoparticle conjugates can be used to target specific tumor cells for detection by MRI.
