A team of researchers from Immanuel Kant Baltic Federal University obtained magnetic nanoparticles using sweet flag (Acorus calamus). Both the roots and the leaves of this plant have antioxidant, antimicrobial, and insecticide properties. The extract of sweet flag was used as a non-toxic reagent for the manufacture of coated particles. The authors of the work also showed the efficiency of the new nanoparticles against several types of pathogenic fungi that damage cultivated plants. A technology developed by the team provides for the manufacture of nanoparticles from a cheap plant-based raw material and reduces the harmful effect of reagents on the environment.
