Hemocompatibility of zinc ferrite nanoparticles (ZnFe2O4 NPs). a Photographs of hemolysis assay to detect the presence of hemoglobin in the supernatant of ZnFe2O4 NPs treated samples. b Hemolysis percentage of ZnFe2O4 NPs treated samples versus positive and negative control. PEG and Triton X-100 lysed blood cells served as a negative control (NC) and positive control (PC), respectively. The values presented in the graph are mean ± SD of triplicate and *p  0.05, ****p  0.0001 were considered statistically significant
