Oxygen-doped carbon nanotubes for near-infrared fluorescent labels and imaging probes

Abstract Chemical modification of carbon nanotube surface can controllably modulate their optical properties. Here we report a simple and effective synthesis method of oxygen-doped single-walled carbon nanotubes (o-SWCNTs), in which a thin film of SWCNTs is just irradiated under the UV light for a f...
