Cover Story: In this study, cerium oxide nanoparticles made from superparamagnetic iron oxide, which exhibit magnetic properties when applied to an external magnetic field, were prepared. Unlike normal cells, cerium oxide nanoparticles have the advantage of effectively inhibiting the growth of cancer cells in the environment of tumor cells, and the prepared nanoparticles were coated with hyaluronic acid to prepare a drug delivery system targeting tumor cells. In addition, natZr was labeled using a chelate, and it can be expected to develop a theranostics drug delivery system by replacing it with 89Zr, a positron-emitting nuclide to be introduced later.
