Structure, magnetic, photocatalytic and blood compatibility studies of nickel nanoferrites prepared by laser ablation technique in distilled water

The main objective of this study is to investigate the structural features, magnetic behaviour, photocatalytic properties and blood compatibility NiFe2O4 nanoparticles (NPs) obtained by subnanosecond laser ablation in water. Structure size distribution NPs were studied using X-Ray Diffractometry (XRD) Transmission Electron Microscopy (TEM). evaluated photo-degradation Methylene Blue (MeB) dye under ambient visible light illumination. Four different kinetic models used identify degradation mechanism it was found that pseudo-second-order model most suitable type interpret experimental data MeB photodegradation. hemocompatibility hemolysis tests human erythrocytes drawn from healthy volunteers. caused undesirable ratios at 0.05, 1 5 mg/ml concentrations, while biologically safe concentration these be below 0.01 mg/ml.
