Hyperthermic triggers for drug delivery platforms.

Electromagnetic fields can penetrate aqueous media in a homogeneous and instantaneous way, without physical contact, independently of its temperature, pressure, agitation degree and without modifying their chemical compositions nor heat and mass transfer conditions. In addition, superparamagnetic biomaterials can interact with electromagnetic fields by absorbing electromagnetic energy and transforming it in localized heat with further diffusion to surrounding media. This paper is devoted to the exploration of the potential use of hyperthermic effects resulting from the interaction between externally applied electromagnetic fields and superparamagnetic nanoparticles as a trigger for controlled drug release in soft tissue simulating materials.
