SUPPORTING INFORMATION Long Circulating Anionic Liposome for Hepatic Targeted Delivery of Cisplatin

Fig. 1 shows the FTIR spectra of GA, AGA-PEG and AGA-PEG-ST. In the spectra of GA, the absorption peaks at 3450 cm-1, 2947 cm-1 and 1650 cm-1 are associated with hydroxyl bonds and alkene bonds of GA, respectively. The broad peak appearing between 3400 and 2500 cm-1 and the peak at 1720 cm-1 are respectively contributed to O-H bonds and carbonyl bonds in carboxylic acid. In the spectra of AGA-PEG and AGA-PEG-ST, the absorption peaks appearing at 1113 cm-1 are contributed to C-O-C in PEG, the peaks at 1735 cm-1 indicates generation of ester bond.
