How does the size of nanoparticles affect plant uptake?
Best insight from top research papers
The size of nanoparticles significantly influences plant uptake. Research indicates that smaller nanoparticles are preferably taken up by plant roots and then can aggregate into larger nanoparticles in plant shoots. Additionally, studies show that metal concentrations in plant shoots increase with decreasing particle size for non-essential elements, while the relationship is variable for essential elements. Furthermore, the uptake of metallic nanoparticles by crops, especially those with sizes below 30 nm, has been extensively studied, with root application being the predominant method. Overall, the size of nanoparticles plays a crucial role in their uptake and accumulation by plants, highlighting the importance of understanding how nanoparticle size impacts plant-nanoparticle interactions.

How does soil pH affect the bioavailability of nanoparticles in plants?5 answersSoil pH plays a crucial role in influencing the bioavailability of nanoparticles in plants. Different pH levels affect the behavior of nanoparticles in soil solutions and their interaction with plant systems. For instance, at higher pH levels, negatively charged ZnO nanoparticles exhibit higher total Zn concentrations compared to neutral and positively charged ones. Additionally, soil pH impacts the dissolution rates of nanoparticles, with higher dissolution observed at lower pH levels. The bioavailability of TiO2 nanoparticles to plants and soil microorganisms is largely affected by soil pH, as these nanoparticles remain mostly in particulate form regardless of the soil's acidity. Understanding the relationship between soil pH and nanoparticle bioavailability is essential for assessing the potential risks and benefits of nanoparticle applications in agriculture.
