Fig. 7. Demonstration of the rubbery property of RNA nanoparticles through renal excretion by comparing tumor and kidney retention time using Ex vivo organ images.

Fig. 7.

The near-infrared AF647 labelled 10 nm and 20 nm squares were detected in the kidney 12 and 24 hrs post systemic injection. Both the 10 and 20 nm RNA squares were excreted through kidney filtration, while with longer retention time in tumor by comparing the organ intensity after 12 hrs.
