Iron oxide nanoparticles coated with aspartic acid and their genotoxic impact on root tip cells of Zea mays embryos

摘要

The goal of the present study was to evaluate the genotoxic influence ofiron oxide nanoparticles coated with aspartic acid (AIONPs) with 9.3 nm physicaldiameters on the root tip cells of Zea mays seeds. The seeds germination occurred underAIONPs presence by addition into the germination substrate of AIONPS aqueoussolutions with different volume fractions (range between 20 and 400 μ/l). For all samples(control and treated samples) indexes of cytogenetic assays were established. Themitotic division of cells seems was stimulated under AIONPs influence (up to 68%)with a low rate of aberrant cells occurrence (up to 1.42%).
