Figure 5
Fluorescent images of SMMC-7721 cells and MCF-7 cells after being incubated for 6 h with different kinds of NPs at the same amount of NPs (0.3 mg/mL), and all of, NPs are labeled by rhodamine B (red). (a) Incubated with CS NPs in SMMC-7721 cells, (b) incubated with unfiltered FA-CS NPs in SMMC-7721 cells, (c) incubated with filtered FA-CS NPs in SMMC-7721 cells, and (d) incubated with filtered FA-CS NPs in MCF-7 cells.
