Particles in tubes: Multiwalled carbon nanotubes containing Fe3C particles (see SEM image) have been prepared by pulse-injection chemical vapor deposition. The Fe3C particles provide the nanotubes with magnetic properties. The use of the nanotubes was also investigated in in vitro drug-release studies.
