Reshaping quantum dots production through continuous flow and sustainable technologies
Researchers have developed a pioneering, sustainable method for producing cadmium-based quantum dots (QDs) in water using a biocompatible chalcogen source. This fully aqueous, continuous flow process avoids harmful organic solvents and offers enhanced safety, scalability, and environmental performance. A collaboration led to the creation of a water-soluble chalcogen transfer agent inspired by peptide chemistry. Real-time Raman spectroscopy enabled detailed analysis of reaction mechanisms. The new system improves productivity while reducing waste and energy use. Although cadmium QDs are efficient, their toxicity remains a concern, prompting the team to explore greener alternatives. This innovation marks a significant step toward responsible, large-scale nanomaterial production.
