Figure 7. Uptakes of free RhB, SDS-RhB and RhB loaded CAB/SDS vesicles by NIH 3T3 cells.
(a) Fluorescence images taken by Olympus IX71 at different incubation times. Scale bars are 20 μm. (b) Mean fluorescence intensity of the treated cells at different time (n = 6). CAB15 and CAB30 show significant differences compared to free RhB and SDS-RhB, respectively (**p < 0.01, Student’s t test).
