  • Publication number: 20220362381
    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.

  • Patent number: 9387152
    Abstract: The invention relates to blood substitute compositions, and methods of use thereof. Described herein are compositions in which hemoglobin is maintained substantially in the reduced form of hemoglobin as opposed to the oxidized methemoglobin form through inclusion of an oxido-reductase enzyme and reducing agent within a vesicle with the hemoglobin. The vesicles additionally can comprise a dismutase, a catalase, and an electron acceptor, each of which contribute to either the maintenance of hemoglobin in the active oxygen carrying state or provide a benefit not achieved with free hemoglobin.
