Effect of Silver Nanoparticles on Plant Growth
The effect of nanomaterials on plant species is a topic that is being widely researched however there is still no conclusive answer on whether nanomaterials, specifically silver nanoparticles, have a negative impact on plant species,The effects observed are highly dependent on the type and concentration of NPs as well as the plant species and growth conditions used in the experiments For example, carbon nanotubes were shown to be able to penetrate plant seed coats and dramatically affect both seed germination and plant growth [ 27 ]Developmental and Reproductive Effects of Iron Oxide
