Fig. 5. (a) Bright field and SWIR fluorescence (>1000 nm) images for different-sized breast tumours (2 mm to 8 mm in diameter). Images were taken three days after the injection of ICG–Herceptin. The red broken circles show the position of a breast tumour. Inset shows ex vivo images of isolated tumours. Scale bar: 1 mm. (b) Bright field and SWIR fluorescence images for the nude mice bearing both breast (KPL-4) and skin tumours (A431). Images were taken three days after the injection of ICG–Herceptin or ICG–Erbitux.
