文摘

CQDs showing strong fluorescence are simply prepared from lysine through microwave assisted pyrolysis. Lysine-based CQDs are less than 10 nm and have amorphous carbonic cores and amine and hydroxyl functionality in their surface. The use of lysine as an AB2 type amino acid possessing branching point is the key for the successful synthesis CQDS. Lysine-based CQDs are highly nontoxic and biocompatible, enabling bioimaging of cellular media with high degree of physiological safety.
