Figure S5. GO, rGO and PEG-rGO solutions (from left to right) in PBS.
Figure S5 shows the solubility of GO, rGO and PEG-rGO after 1 hour of PBS treatment and 10 minutes of centrifugation at 14000 rpm. Both GO and rGO were insoluble after mixing with cisplatin solution, while PEG-rGO showed no aggregation.
