Indian researchers develop method to produce carbon nanoparticles from bagasse

In India, researchers led by the National Centre for Nanoscience and Nanotechnology at the University of Madras have developed a way to produce highly fluorescent carbon quantum dots— tiny carbon nanoparticles, which are about four nanometers across—from sugarcane bagasse. They can be used as biosensors, in light-emitting diodes and even to deliver drugs around the human body, providing a much higher value product that animal feed, electricity through cogeneration or cellulosic ethanol at what the researchers say is a simple, low-cost and efficient method.
