		Single-walled nanotubes (SWNTs) are non-destructively oxidized along their sidewalls and covalently functionalized with metal nanoparticles via carboxylate chemistry. Proteins adsorb individually, strongly and non-covalently along nanotube lengths, as seen on individual nanotube reaction products in atomic force microscopy. SWNT electrodes possess striking attributes and can be used to assess the electronic properties of functionalized nanotubes. Electrochemistry reveals that proteins adsorbed on nanotubes remain intact and retain redox and catalytic activity. Such chemical treatment, biochemical functionalization, and measurement of electrochemical properties present a powerful means for constructing novel nanotube-based sensors.
