Keywords: , , ,

Cobalt ferrite magnetic nanoparticles (MNPs) were prepared by co-precipitation being further electrostatically stabilized in solution (particularly used in experimental cancer treatment through hyperthermia). We focused on the biological impact of MNPs following their release in the environment  mainly the oxidative stress induced in some microorganisms: cellulolytic fungi: Phanerochaete chrysosporium and Trichoderma viride (able of degrading cellulose waste). XRD provided typical spinel structure, SEM data revealed a 45 nm physical diameter, magnetometric investigation evidenced ferrimagnetic properties overlapped onto superparamagnetic ones, while dynamical analysis of particle movement in diluted solution indicated a 65 nm hydrodynamic average diameter. Increased activity of superoxidedismutase (with about 12%, p
