Graphene quantum dots (GQDs) induce antioxidative damage, alteration of phytohormone levels and mineral homeostasis, which eventually cause impaired photosynthesis and plant growth. Surface functionalization determines the reactive oxygen species generation and antioxidants oxidation capacity, which leads to different phytotoxicity of GQDs.
