Particles and related methods are disclosed. The particles have an' impedance of at most 60 ohms at an applied power of two Watt, wherein the particles have a diameter of at most about 3,000 microns. The particles comprise a gelling precusor (e.g. alginate), and at least one polymer (e.g. polyvinyl alcohol) and optionally a ferromagnetic material. In some embodiments, the particles can be used to enhance tissue heating and/or ablation procedures or to transmit RF radiation. |
