Layer-by-Layer (LbL) microcapsules with iron oxide nanoparticles facilitate smart drug delivery in the presence of an alternating magnetic field. A high-frequency alternating magnetic field (AMF) has been commonly used to induce hyperthermia for killing tumor tissues. This technique, however, could harm normal tissues.

Although combining BRAF and MEK inhibitors can shrink tumors, resistance often develops.
