Efficient synthesis of O-doped SWCNTs and their application in fluorescence in vivo imaging. a Schematic diagram of the flow reactor incorporating syringe pumps and a 300 nm LED for irradiation and fluorescence excitation. Emission was collected through the back cell window and analyzed in a SWIR spectrometer. b Emission spectrum of O-doped SWCNTs synthesized in the flow reactor. The solution was diluted by SDC to OD ~0.1 for measurement. (Inset) Photo of O-doped (6,5)-SWCNTs collected directly from the flow reactor. c SWIR fluorescence images of O-doped SWCNTs in vivo. Left panel: a black mouse injected intravenously with ~100 ng of O-doped SWCNTs, showing clear inguinal lymph node. Upper right panel: lymphatic drainage after footpad injection (~10 ng) into a white mouse. Lower right panel: clear vasculature imaging from the leg of a black mouse injected with ~100 ng of O-doped SWCNTs. LN lymph node, A&V artery and vein
