The impact of copper oxide nanoparticles on plant growth: a comprehensive review
Gábor Feigl
Abstract
Copper oxide nanoparticles (CuO NPs) are a type of nanomaterial with unique physical and chemical properties that make them useful in various applications. CuO NPs have been studied for their potential agricultural applications, where they can have both positive and negative effects on plants, depending on factors such as concentration and duration of exposure. CuO NPs have been shown to improve plant growth and development by enhancing photosynthesis, nutrient uptake, and root growth. However, high concentrations of CuO NPs can cause oxidative stress and damage to plant cells, resulting in reduced growth and yield. Furthermore, these NPs can be taken up by plants and accumulate in various plant tissues, raising concerns about their potential impact on human health if ingested via the food chain. Further research is needed to determine the safe and effective application method and optimal concentration of CuO NPs in agriculture.
