Fig. 2. Haemolytic assay of SPIONs (A) the haemolysis rate of the RBCs incubated with different concentrations of the various SPIONs. (B) Pictorial comparison of different concentrations of SPIONs with and without RBCs. The left photo shows SPIONs, while the right photo shows SPIONs and RBCs after the same treatment. Triton X-100 and PEG were used as positive and negative controls, respectively.
