Graphene oxide (GO) was firstly prepared by modified Hummers method. In order to improve its water solubility and biocompatibility, 6-arm PEG was grafted to GO via a facile amidation reaction. The size of obtained GO-PEG was less than 250 nm. Stability test indicated the good dispersibility of GO-PEG in water and PBS buffer. Furthermore, eriocalyxin B, a widely used cancer chemotherapy drug, is adsorbed onto GO-PEG via physical blending with a drug loading ratio of 18.8% obtained by UV spectrum. Lung cancer cell A549 and breast cancer cell MCF-7 were selected to study the cytotoxicity of GO-PEG/eriocalyxin B, GO-PEG, and free eriocalyxin B. The results demonstrated that GO-PEG nano-carrier possessed low toxicity (relative cell viability>85%), even cultivated for 48 h at a relatively high concentration of 100 mg/L. Compared to pure drug, GO-PEG/eriocalyxin B nanocarrier shows higher cytotoxicity in A549 and MCF-7 cells.

Key words: graphene oxide, eriocalyxin B, drug delivery, cell viability
