Abstract: This disclosure provides particles that are suitable for remotely-triggered therapy for cancer and microbial infection. In an embodiment, this disclosure provides a particle heater comprising a carrier admixed with a material that interacts with an exogenous source; wherein the material absorbs and converts the energy from the exogenous source into heat, then the heat travels outside the particle heater to induce localized hyperthermia at a temperature sufficient to selectively kill unwanted cells, and further wherein the particle heater structure is constructed such that it passes the Extractable Cytotoxicity Test.

Abstract: This invention provides particles encapsulating colorant that do not produce functional effects or remove functional effects until they are triggered by contacting with at least one exogenous source. The particles in this invention minimize toxic effects the body of the colorant and the material that interacts with an exogenous source as well as minimize body chemicals from degrading both the colorant and the material that interacts with an exogenous source inside the particle.

Abstract: This invention provides particles encapsulating active agent that do not produce functional effects or remove functional effects until they are triggered by contacting with at least one exogenous source. The particles in this invention minimize toxic effects to the body of the active agent and the material that interacts with an exogenous source as well as minimize body chemicals from degrading both the active agent and the material that interacts with an exogenous source inside the particle.
