Implant-mediated targeted drug delivery without an external magnetic field is very challenging. In this work, we report targeted nanodrug delivery initiated by a Fe3O4/poly(lactic-co-glycolic acid) implant scaffold with high magnetism. The implant scaffold is biocompatible and durable. It effectively attracts nanodrugs to its surface, thus killing cancer cells. These findings provide a proof of concept for the magnetic implant-directed nanodrug targeting without the need for an external magnetic field. This approach may further facilitate more precise medical treatments.
