Figure 7 :Optical images of athimic mice after intraperitoneal injection of 500 μl of #SLN-CG-P80. Images were recorded after 4 h from the injection. In vivobody distribution of lipid nanoparticles, as determined by fluorescent luminescent imaging technology of total body.Pictures show the images collected from 2 representative animals that were treated, as described in the experimental section, with a dispersion of nanoparticles by intraperitoneal administration. Dorsal (A-D) and ventral (E-H) images were recorded after the administration of fluorescent nanoparticles (#SLN-CG-P80) (A, B, E, F) or blank, control nanoparticles (#SLN-P80) (C, D, G, H). Colour bar on the right side indicates the signal efficiency of the fluorescence emission coming out from the animal. For nanoparticle identification codes, composition and preparation procedure, please refer to Table 1 and experimental section.
