Nanomaterials for enhancing photosynthesis: interaction with plant photosystems and scope of nanobionics in agriculture Chanchal Mony, Pawan Kaur, James Rookes, Damien Callahan, S. V. Eswaran, Wenrong Yang and Palash Kumar Kumar Manna Abstract The complex process of photosynthesis requires precise arrangements of light harvesting molecules in the photosynthetic system. Artificial imitation of such reaction systems is difficult as they involve complex protein structures.
