Methods And Compositions For X-Ray Induced Release From Ph Sensitive Liposomes, Daniel Fologea, Ralph Henry, Greg J. Salamo, Yuriy Mazur, Michael J. Borrelli

Patents Granted

Compositions including pH sensitive lipid vesicles comprised of a lipid layer, an agent, and an organic halogen such that the agent is released from the vesicles after exposure to ionizing radiation. Methods of delivering the agent to a target in a subject using the compositions provided herein are also described. The methods allow for controlled release of the agent. The timing of release of the agent from the lipid vesicle may be controlled as well as the location of release by timing and localizing the exposure to ionizing radiation exposure.
