Panday et al. discussed the utilization of MIONPs for tumor imaging by injecting a specific concentration of these NPs into the body and guiding them to the tumor site using an external magnet, providing contrast for imaging.112 This method showcases the capability of MIONPs to be directed to specific locations, which could be pivotal for targeting PSMA-expressing prostate cancer cells. The gene discussed is FOLH1; the disease is neoplasm.
