Carbon nanotube chirality
WebAug 11, 2024 · Single-Chirality Near-Infrared Carbon Nanotube Sub-Cellular Imaging and FRET Probes Applications of single-walled carbon nanotubes (SWCNTs) in bioimaging and biosensing have been limited by difficulties with isolating single-chirality nanotube … WebThe chirality describes both the orientation and diameter to which the sheet is rolled. Each SWNT on the chirality map is defined by two integers, (n,m). Chirality defines many of the properties of the individual SWNT. For example, SWNT shown on the chirality map in blue are metallic in nature.
