A separate issue: The underlying mechanism of the unusual selective adsorptions of pyrene and pyrenyl-N-oxide on neutral semiconducting single-walled carbon nanotubes (SWNTs), and of amine, H2O2, and porphyrin on oxidized semiconducting SWNTs (see picture) versus their metallic counterparts is studied. Density functional theory shows that the hole doping of SWNTs can affect the selectivity of a molecule towards them.
