Figure 5.

Ex vivo FRI analysis of the accumulation of the Cy7-labeled micelles and the Cy5.5-based model drug in tumors and healthy organs. (A) Representative images, obtained at wavelengths of 750 nm (micelles) and 680 nm (model drug) are shown. (B) Quantification of the ex vivo images of micelle and model drug accumulation exemplify effective and relatively selective targeting to tumors.
