EGFR and neoplasm: Another example is an active targeting nano-sized theragnostic superparamagnetic iron oxide (SPIO) platform for significantly increasing the imaging sensitivity and energy deposition efficiency in the MDR tumor model using a clinical MRgFUS system which was developed by Wang, Z. et al. The surfaces of these PEGylated SPIO nanoparticles (NPs) were conjugated with anti-EGFR (epidermal growth factor receptor) monoclonal antibodies (mAb) for targeted delivery to lung cancer with the EGFR overexpression (Wang et al., 2017) (Figure 4D).
