ABSTRACT
Rapid development and wide applications of nanotechnology brought about a significant increment on the number of engineered nanomaterials (ENs) inevitably entering our living system. Plants comprise of a very important living component of the terrestrial ecosystem. Studies on the influence of engineered nanomaterials (carbon and metal/metal oxides based) on plant growth indicated that in the excess content, engineered nanomaterials influences seed germination. It assessed the shoot-to-root ratio and the growth of the seedlings. From the toxicological studies to date, certain types of engineered nanomaterials can be toxic once they are not bound to a substrate or if they are freely circulating in living systems. It is assumed that the different types of engineered nanomaterials affect the different routes, behavior, and the capability of the plants. Furthermore, different, or even opposing conclusions, have been drawn from most studies on the interactions between engineered nanomaterials with plants. Therefore, this paper comprehensively reviews the studies on the different types of engineered nanomaterials and their interactions with different plant species, including the phytotoxicity, uptakes, and translocation of engineered nanomaterials by the plant at the whole plant and cellular level.

Mentions: Graphene is a two dimensional crystalline allotrope of carbon, which can be described as a one atom layer of graphite. At high concentrations of graphene (1000 mgL−1), the root hair growth of red spinach and cabbage decreased compared to the control plant [117–119] (Figure 5). This is due to the accumulation of graphene using H2O2 visualization, together with visible signs of necrotic damage lesions and proof of a massive electrolyte leakage, indicating an oxidation stress mechanism [28, 118, 120].
