Claim Text:
1. A method of at least partially separating a first type of carbon-based nanostructure from at least one second type of carbon-based nanostructure, comprising: providing a plurality of porous magnetic particles, wherein each of the plurality of porous magnetic particles comprise a plurality of nanoparticles associated with the magnetic particles; exposing the plurality of porous magnetic particles to a mixture of carbon-based nanostructures comprising the first type of carbon-based nanostructure and the at least one second type of carbon-based nanostructure, wherein the first type of carbon-based nanostructure is attracted to and/or associates with the porous magnetic particles to an extent greater than that of the at least second type of carbon-based nanostructure; and at least partially separating the porous magnetic particles from the mixture of carbon-based nanostructures, thereby collecting a set of carbon-based nanostructures that is enriched in the first type of carbon-based nanostructure.
