Fig. 5. Red blood cell (RBC) viability assay. RBCs were incubated with different concentration (0.5 to 100 μg mL−1) of GO, GO-A, or GO-AL. (A) Graphic representation of RBC viability was determined based on the degree of hemolysis. Data are the mean ± standard deviation for three separate experiments. (B) Photographs of RBCs treated with GO samples. PBS and DI water served as the negative (−) and positive (+) controls, respectively. The experiments were repeated in triplicate.
