Nanotubes released: π–π stacking interactions between single-walled carbon nanotubes (SWCNTs) and a monolayer of aromatic rings anchored on a gold surface result in reversible surface assembly of the SWCNTs. Protonation of a pyridine-based self-assembled monolayer reduces the pyridine–SWCNT interaction and thus releases the SWNCTs (see picture).
