Intracellular location of FA/PEI-OA/LOR-2501 complexes in HeLa cells. NPs co-localized with Tf-A488 (endosomes), FITC-dextran (macropinosomes), and cholera toxin B Alexa 488 (caveosomes) separately after 1 h incubation. The Cy3-LOR-2501 is shown in red, the cellular markers are shown in green, and overlay of Cy3-LOR-2501 and markers is shown in yellow. White arrows indicate the co-localization.
