These include Transcranial Magnetic Stimulation and Transcranial Direct Current Stimulation, the former uses alternating magnetic fields to simulate specific brain areas while the latter aims electrical currents of power equal to a 9 - volt battery to specific brain areas. (aaas.org)
Previous cancer studies had shown that by injecting tumors with magnetic nanoparticles made of iron oxide — «essentially rust, with well - tuned magnetic properties,» Anikeeva says — then exposing them to rapidly alternating magnetic fields, excited nanoparticles can be used to heat and destroy cancer tumors while leaving surrounding, healthy tissue intact.

They subsequently co-encapsulated the cells with magnetic iron oxide in immunoprotective alginate microcapsules and then remotely triggered cytosine deaminase expression by alternating magnetic field - induced hyperthermia. (sciencedaily.com)
