NIR-II intraoperative imaging of invisible liver cancer under white light. (a ∼ b) Color and BLI images during the surgery. Step 1: before resection. Step 2: first resection. Step 3: second resection. (c) NIR-II fluorescence-guided surgery process. The mouse was repeatedly imaged until no BLI signal was detected in the liver. (d) Size analysis for the 2 lesions. (e ∼ f) Intraoperative HE staining of the above 2 lesions. (Scale bars: 1000 μm, 50 μm). Imaging filter:1000 nmLP. Exposure time:300 ms–1000 ms. Excitation wavelength:808 nm. Laser power density: 21.10 mW/cm2. Imaging field of view: 10 cm.The type of camera sensor: InGaAs.
