A Chinese research team has developed a carbon based nanomaterial from agricultural waste biomass that can enhance plant photosynthesis and potentially boost crop growth,
according to their study recently published in Communications Materials.
The researchers from Shenzhen Institute's Study of Advanced Technology under the Chinese Academy of Sciences and Shanghai Jiaotong University developed the Carbon Quantum Dots,
a carbon based nanomaterial synthesized from agricultural waste from biomass such as straw,
leaves and weeds.
The new material converts ultraviolet light, which plants cannot absorb,
and green light, which they absorb inefficiently, into red light for more efficient absorption.
It also excites electrons from absorbed photons to provide additional electrons for the photosynthetic electron transport chain,
thus improving the photosynthesis efficiency.
The researchers put the material into the liquid culture medium of cyanobacteria or sprayed it on plants for experimentation.
The material not only improves photosynthetic efficiency and promotes plant growth,
but also offers the advantages of low cost and high biocompatibility,
making it highly promising for future agricultural production and solar powered biomanufacturing.
Preliminary experiments also show
that the material can promote the growth of plants such as duckweed,
peanuts, corn and soybeans.
