Biosynthesis of magnetite and cobalt ferrite nanoparticles using extracts of "hairy" roots: preparation, characterization, estimation for environmental remediation and biological application.

ABSTRACT: The "green" synthesis of magnetite and cobalt ferrite nanoparticles (Fe₃O₄-NPs and CoFe₂O₄-NPs) using extracts of Artemisia annua L "hairy" roots was proposed. In particular, the effect and role of important variables in the 'green' synthesis process, including the metal-salt ratio, various counter ions in the reaction mixture, concentration of total flavonoids and reducing power of the extract, were evaluated. The morphology and size distribution of the magnetic nanoparticles (MNPs) depended on the metal oxidation state and ratio of Fe(iii) : Fe(ii) in the initial reaction mixture. MNPs obtained from divalent metal salts in the reaction mixture were non-uniform in size with high aggregation level. Samples obtained by the FeCl₃/
