Short carbon nanotubes as adsorption and retention agents

Abstract

A method for delivering a radiotherapeutic agent to a target, comprises administering a composition comprising water-soluble nanotubes having an average length less than 50 nm and a radionuclide so as to expose the target to the composition. The nanotubes can be functionalized with a monoclonal antibody having an affinity for the target. The radionuclide can be contained in the nanotubes, which can be derivatized. The nanotubes can be loaded with I2 or 211AtI, another α-emitter, including but not limited to 211AtI, 225Ac, 212Bi, 213Bi, and combinations thereof. The nanotubes have an average length less than 40 nm, or an average length less than 30 nm.
