Figure 4From: Highly enhanced optical properties of indocyanine green/perfluorocarbon nanoemulsions for efficient lymph node mapping using near-infrared and magnetic resonance imaging Cell fluorescence imaging with the PFC/ICG nanoemulsions. Fluorescence images of HeLa (A to C), DC2.4 (D to F), and Raw264.7 (G to I) cells after incubation with the PFC/ICG nanoemulsions. The PFC/ICG nanoemulsions are red, and the DAPI-stained nuclei are blue. Bar, 15 μm.Back to article page
