Physiological investigation of magnetic iron oxide nanoparticles towards Chinese mung bean.

While few publications have documented systematic physiological effects of nanoparticles on plant cells and tissues, this is the first study describing a detailed evidence of impact of gamma-Fe2O3 magnetite nanoparticles (MNPs) on Chinese mung bean plants by measuring the physiological parameters such as germination, root activity, activity of catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD), content of chlorophyll, soluble protein, and content of malondialdehyde (MDA). Our results will help answer the question on how both positive and negative or inconsequential effects take place in plants after treatment by the nutrient solution containing nanoparticles.
