Dual‐channel NIR‐II fluorescence imaging‐guided lymphadenectomy on rats. a) Brief description of the process. b) i) The precisely located mesenteric LNs labeled with IDSe‐IC2F NPs under 793 nm laser excitation; ii) dual‐channel fluorescence imaging of LNs and blood vessels (labeled with TQ‐BPN NPs) under the excitation of both 793 nm laser and 623 nm LED; iii) the process of resection (two LNs were detected and removed); iv) no obvious bleeding was observed; v) no residual LN was detected. Scale bar: 10 mm. c) i) The located gastric LNs labeled with IDSe‐IC2F NPs under 793 nm laser excitation; ii) dual‐channel fluorescence imaging of LNs and gastric vessels (labeled with TQ‐BPN NPs) under the excitation of both 793 nm laser and 623 nm LED; iii) the process of resection (the LN was very close to the left gastric artery); iv) no obvious bleeding was observed; v) no residual LN was detected. Scale bar: 10 mm. Red circles: the position of LNs (after resection).
