Fig. 1. In vivo fluorescence images of Cy5.5-labeled HA-NPs (A) and Cy5.5-labeled HA-polymers (B) in the whole body (n = 6) at 0.5 h, 2 h, 4 h, 1 day (d), 3 d, 7 d, 14 d, and 28 d. Tail vein injection of Cy5.5-labeled HA-NPs or HA-polymers (5 mg/kg) in normal hairless mouse. The fluorescence of HA-NPs was much stronger than that of HA-polymers and was maintained longer within the experimental period relative to HA-polymers. The liver and urinary bladder were the main organs that showed strong fluorescence in both groups. Becoming yellow indicates a higher intensity of fluorescence at 680 nm. Normal, untreated mice.
Fig. 2. Ex vivo fluorescence images of Cy5.5-labeled HA-NPs (A) and Cy5.5-labeled HA-polymers (B) in different organs (brain, thymus, sublingual gland, heart, lung, liver, spleen, kidney, adrenal gland, testis and epididymis; n = 6) at 0.5 h, 2 h, 4 h, 1 d, 3 d, 7 d, 14 d, and 28 d. Tail vein injection of Cy5.5-labeled HA-NPs or HA-polymers (5 mg/kg) in normal ICR mice. Generally, the overall fluorescence of HA-NPs was stronger than that of HA-polymers and was maintained longer during the experimental period. The liver, spleen, kidney and lung were the main organs that showed strong fluorescence in both groups. Becoming yellow indicates a higher intensity of fluorescence at 680 nm. 1, brain; 2, sublingual glands; 3, thymus; 4, heart; 5, lung; 6, stomach; 7, liver; 8, spleen; 9, adrenal glands; 10, kidneys; 11, testes; 12, epididymes.
Fig. 3. Fluorescence intensity (106 photons/sec/cm2) of total organs from 0.5 h to 28 d after injection of 0.5 mg/kg of Cy5.5-labeled HA-NPs (A) or Cy5.5-labeled HA-polymers (B). The main organs that showed a high intensity of fluorescence were the liver, lung, spleen, kidney, testis and sublingual gland in both groups. Generally, the intensity of fluorescence peaked within 4 h, then decreased gradually with time. The intensity of Cy5.5-labeled HA-NPs (A) was much stronger than that of Cy5.5-labeled HA-polymers (B). Data are expressed as the means ± SE (n = 6).
Fig. 4. Fluorescence intensity (106 photons/sec/cm2) in the liver (A), spleen (B), kidney (C), lung (D), testis (E) and lymph node (F) from 0.5 h to 28 d after injection of 0.5 mg/kg of Cy5.5-labeled HA-NPs or Cy5.5-labeled HA-polymers. The intensities of Cy5.5-labeled HA-NPs were much stronger level than those of Cy5.5-labeled HA-polymers. Generally, the intensity of fluorescence peaked within 4 h, then decreased gradually thereafter. However, the lymph node showed more powerful intensities of fluorescence in HApolymers within the experimental period than HA-NPs. ap < 0.05 between HA-NPs and HA-polymers. b,cp < 0.05 compared with the intensity of 0.5 h. Data are expressed as the means ± SE (n = 6).
