ABSTRACT:
A method of localized cell heating introduces a plurality of ferroelectric comprising particles into a target region of a patient, and applies a time varying electrical field to the target region. The ferroelectric particles absorb energy from the electrical field and heat the target region in response, such as to a temperature sufficient to induce apoptosis of cancer cells in the target region. A ferroelectric hyperthermia-based cancer treatment system includes a time varying electrical field source for applying a time varying electrical field to a plurality of ferroelectric particles disposed in a target cancer containing region of a patient. A composition of matter includes a particle having a ferroelectric portion, the particle being non-toxic, slowly biodegradable in body fluids, and less than 15 μm in its maximum dimension.
