²¹¹AtCl@US‐Tube Nanocapsules: A New Concept in Radiotherapeutic‐Agent Design

Abstract

Get shorty: Ultrashort carbon nanotubes (US-tubes) ranging in length from 20–50 nm have been loaded internally (see image) with an α-emitting radionuclide (At-211) for targeted radiotherapy. By loading the radionuclide inside the carbon nanotube as a mixed halogen (211AtCl), the 211AtCl@US-tube nanostructures offer a new paradigm in radiotherapeutic containment and delivery as the first carbon-nanotube-based radiotherapeutic agent.
