Abstract
Described herein are devices for applying an alternating electric field to a living subject or an in vitro medium at a frequency between 100 kHz and 500 kHz. Also described herein are methods of using the described devices for applying an AC electric field to a target region comprising rapidly dividing cells, e.g., cells associated with a variety of disorders or conditions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
Claims20
An apparatus for applying an alternating electric field to a living subject or an in vitro medium at a frequency between 100 kHz and 500 kHz, the apparatus comprising:
- a layer of conductive material having a front face, the front face having an area;
- a flexible polymer layer positioned against the front face of the conductive material so as to cover at least a portion of the area, the polymer layer having a front face;
- and
- an electrical lead positioned in electrical contact with the layer of conductive material,
- wherein the polymer layer comprises at least one polymer selected from Poly(VDF-TrFE-CTFE), Poly(VDF-TrFE-CFE), and Poly(VDF-TrFE-CFE-CTFE).
