Figure 2

Size distribution of poloxamer188-b-PCL NPs (A), SEM image of cargo-free NPs (insert, left), and poloxamer188-b-PCL NPs solution (insert, right). The average diameter of the obtained NPs was 119.9 ± 0.5 nm with a PDI of 0.03 ± 0.02; the different stability of cargo-free NPs in various NaCl solution (B). The cargo-free NPs showed an excellent stability in NaCl solutions; the thermo-stability of cargo-free NPs (C). The size distribution of poloxamer188-b-PCL NPs in BSA solution (D). After 60 min incubation under 80oC, the cargo-free NPs had good stability; the stability of cargo-free NPs in 10% BSA solution; Cytotoxicity of the cargo-free NPs (E). Cell results indicated that the poloxamer188-b-PCL NPs did not show obvious cytotoxicity.
