Figure 1From: Internalization and cytotoxicity of graphene oxide and carboxyl graphene nanoplatelets in the human hepatocellular carcinoma cell line Hep G2 Size distribution of GO and CXYG in stock suspensions determined by means of DLS. GO (A) and CXYG (B) stock suspensions diluted to concentrations of 16 and 32 μg/ml, respectively, were analyzed by means of DLS. The graphs show the average hydrodynamic size distribution by intensity of at least four measurements consecutively conducted on each sample.Back to article page
