a The diagrammatic drawing of the fabrication process of IDSe-IC2F and the results of TEM and DLS. b NIR-II images of popliteal and sciatic LNs at different time points and NIR-II imaging-guided lymph node resection. c Precise positioning of mesenteric lymph nodes marked by IDSe-IC2F NPs and dual-channel fluorescence imaging guide lymphadenectomy on mesentery. d The location of gastric LNs labelled with IDSe-IC2F NPs and gastric vessels identified with TQ-BPN. i–iv: the process of resection of LNs closely to the left gastric artery. e Triple-channel NIR fluorescence images of paraaortic LNs (IDSe-IC2F), blood vessels (TQ-BPN NPs), and ureters (PEG-CSQDs) on rats with different excitation light sources (623 nm and 793 nm), the insert shows that triple-channel fluorescence imaging guide the lymphadenectomy beside the abdominal aorta.
