Targeting ability and Targeted transfection ability of the LPPC/RBDV complexes in vivo. a Tumour-bearing mice were i.v. injected with LPPC/DiO/RBDV or LPPC/DiO/IgG1 Fc. After 72 h, the organs and tumours were excised and imaged with an IVIS system at the appropriate wavelength (Em: 600 nm and Ex: 465 nm). b Tumour-bearing mice were i.v. injected with LPPC/pAsRed/RBDV or LPPC/pAsRed/IgG1 Fc. After 6 days, the organs and tumours were excised and imaged with an IVIS system at the appropriate wavelength (Em: 560 nm and Ex: 465 nm). c The tumours and organs were further processed by H&E staining and photographed with a fluorescence microscope. LPPC, which encapsulated with RBDV or IgG1 Fc, were all complexed by PEG
