Indian researchers have found a new use for sugarcane pulp, as a source of highly fluorescent carbon quantum dots, in a study published in Applied Surface Science. This alternate use of sugarcane waste, or bagasse, could not only reduce the amount of agricultural waste contaminating the environment but also offers a new revenue stream for farmers.
“In our study, we developed a simple, low-cost and efficient method for green synthesis of fluorescent carbon quantum dots from sugarcane bagasse,” says Dr. Ravi Shankaran Dhesingh, National Centre for Nanoscience and Nanotechnology at the University of Madras, Chennai, India.

These dots are tiny carbon nanoparticles, which are abou...
