Photosynthesis is highly sensitive to environmental stress, which can limit plant growth and crop productivity. Nanoparticles (NPs) present novel opportunities to enhance photosynthetic efficiency by influencing pigment synthesis, light-harvesting complexes, photosystem activity, electron transport, carbon fixation, and related gene expression. However, NP effects are highly dose- and context-dependent, necessitating a detailed mechanistic understanding and safe-by-design approaches to ensure their sustainable and environmentally responsible application in agriculture.
