Imaging of CSA-BP-modified INPs in vivo. (A) Nude mice bearing Fluc-GFP-JEG3 tumors (left row) were intravenously injected with the CSA-INPs or INPs (1 mg/kg ICG equivalent). Mice were sequentially imaged from 10 min to 48 h using an IVIS spectrum imaging system. (B) Quantification of the IVIS signal from the Fluc-GFP-JEG3 tumors at different time intervals from 10 min to 48 h after the CSA-INPs injection. (C) Immunofluorescence staining of Fluc-GFP-JEG3 tumor tissues 48 h after the CSA-INPs intravenous injection. The sections were imaged using confocal microscopy. Scale bar: 20 μm.
