Dio delivered by ScFv-PEG2000-DSPE into RT112 cells in vitro. The immunoliposomes or liposomes containing 0.1% Dio were incubated with RT112 cells and T24 cells in cell incubator for 3 h in the dark. Hoechst 33342 was used to label cell nuclear. The left panel displayed the green Dio in different treatment groups, the middle panel showed the blue cell nuclear stained by hoechst 33342, and the right panel showed merged figures of two colors. The cells were observed under a fluorescent microcopy. Bar = 50 μM
