Highlights
Impacts of magnetic nanoparticles on the C. vulgaris cells were investigated.
Growth inhibitory effect was seen at concentrations ≥400 µg/mL.
Significant effects on chloroplast and mitochondrial activity occurred at ≥50 µg/mL.
Microalgal cells could overcome the imposed damages after certain days.
