Recent trends in the use of green sources for carbon dot synthesis–A short review

Carbon dots, a class of zero dimensional nanomaterials have recently emerged as excellent candidates for versatile applications such as bioimaging, catalysis, sensing and drug delivery. They possess outstanding optical properties, low toxicity, high biocompatibility, and require simple low-cost synthesis methods. Both top-down and bottom-up approaches have been developed for the synthesis since its discovery. Various techniques such as laser...
