Chinese scientists create carbon-based nanomaterial to boost crop growth and photosynthesis efficiency

A team of Chinese scientists has created a carbon-based nanomaterial derived from agricultural waste that significantly enhances plant photosynthesis, offering a potential breakthrough in crop growth and agricultural productivity.

The carbon quantum dots are synthesised from organic waste materials such as straw, leaves, and weeds. This is reported by China Daily, a partner of TV BRICS.

According to researchers, the nanomaterial converts ultraviolet light, which plants cannot absorb, and green light, which they absorb inefficiently, into red light – a wavelength optimised for photosynthesis. Additionally, it facilitates the photosynthetic electron transport chain by providing extra electrons, further improving energy conversion.

Early tests also indicate the material stimulates growth in key crops such as duckweed, peanuts, corn, and soybeans.

With its low cost, high biocompatibility, and sustainable nature, this innovation holds potential for agricultural production and solar-powered biomanufacturing. The research team is now preparing for large-scale field trials to validate the nanomaterial’s effectiveness in real-world farming conditions.
