MTT assay to measure the cytotoxicity of Bi(PEG-PLA)-Pt(IV) NPs against A2780 human ovarian carcinoma cell line in comparison with cell culture media, PEG-PLA NPs and free cisplatin (10 μM, 50 μM and 100 μM). The amount of cisplatin loaded in the Bi(PEG-PLA)-Pt(IV) NPs was equivalent to 7 μM free cisplatin drug. All samples were incubated with cells for 4 hrs, and the cells were subsequently washed and incubated for a total of 72 hrs before assessing cell viability in each group (n=6).
