(a) Representative in vivo fluorescence images of MGC803-tumour-bearing mouse after iv-injected with FA-AlexaFluor647-labeled pRNA nanoparticle. The tumor areas are indicated with arrows. (b) Representative ex vivo images of tumors and organs. Labels: 1, tumor; 2, heart; 3, liver; 4, spleen; 5, lung; 6, Stomach; 7, kidneys; 8, bladder; 9, muscle. (c) The average fluorescence intensities from the tumor areas of post-injection (3 mice per time point). The error bars represent SEM (n = 3).
