single-walled carbon nanotubes

Referred to as SWCNTs, these cylindrical nanostructures composed of a folded sheet of graphene can be used as near-infrared markers for small animal multiplex imaging. Emitting at different wavelengths, which can be tuned in the visible or NIR region, SWNCTs provide photostable, narrow bandwidth fluorescence in a wide chromatic variety. That enables simultaneous imaging of a large number of spectrally separated markers, through the use of global hyperspectral imaging. In addition to being used as a biological marker, SWCNTs are also used for energy storage and they are implemented in electronic devices because of their high carrier mobility. Their electronic properties are related to their structure (chirality).
