Seyed Yahya Moradi, electromagnetic stimulator are being used for thermoresonsive drug delivery. This involves loading of paramagnetic nanoparticles or magnetized polymers (by Gd addition) in drug delivery systems (DDS). After in vivo application, electromagentic field is applied externally which activates paramagnetic nanoparticles and produce heat. In response to heating, DDS will either break down or undergo phase change and drug is released. In the following paper you can search magnetic or thermoresponsive liposomes for reference.
