False-color near-infared fluorescence intensity maps of the ventral aspect of a mouse prior to injection with Alexa Fluor 750 labeled vesosomes and at 5 min, 1 hr, 2.5 hr and 3.5 hr, following injection. The red is body autofluorescence detected at 700 nm and the green is fluorescence detected at 800 nm due to the labeled vesosomes.
