A scanning electron microscope (SEM) image of a similar RNAi microsponge from the same reaction mixture, representing one of the commonly formed sample morphologies, is shown for comparison (Fig. 1e).

(Nanowerk Spotlight) Carbon nanotubes are attractive materials as the building block of quantum-dot based nanodevices. In particular, single-wall carbon nanotubes (SWCNTs) are interesting because they ...
