Aim: The aim of this study was the synthesis of ion doped silica-based nanoparticles and the evaluation of their toxic effect on erythrocytes. Materials & methods: Their synthesis was performed using the sol-gel method, by the progressive addition of calcium, magnesium and copper ions on pure silica nanoparticles. The toxicity evaluation was based on hemolysis, lipid peroxidation, ROS, H2O2 species and antioxidant enzyme production. Results: The addition of Mg and Cu in the SNs presented better hemocompatibility by protecting erythrocytes from oxidative stress. Conclusion: Ion doping with magnesium in the investigated calcium silicate system induces a protective effect in erythrocyte membrane in compare with pure silica nanoparticles.
