Uptake and Translocation of Zn, Mn, and Ce NPs by soybean (Glycine max (L.) Merrill plants

Abstract

Gabriel Sgarbiero Montanha

Nanomaterials are a promising source ofnutrients for plants, with an extraordinary potential to boost the yield on crops. In this scenario, an investigation on the interactions among engineered-nanoparticles (ENPs) and agricultural plants is under a skyrocketing. In this context, this work aims to present an overview regarding seed, root, and foliar exposure of ZnO, MnO, and CeO2 NPs to soybean (Glycine max (L.) Merrill plants. As part of an integrative, multidisciplinary approach, these studies employed elemental and optical techniques, e.g., benchtop and synchrotron-based X-ray fluorescence and absorption spectroscopy (XRF and XANES), Single Particle Inductively Coupled Plasma Mass Spectrometry (SP ICP-MS), and ScanningElectronic Microscopy (SEM), to evaluate the uptake, translocation, and physiological effects of the NPs, which might shed light into the plant and nanoparticles interactions in order to ensure its reliable in-field application on crops.
