Carbon dots (C-dots) are nanoparticles composed of carbon with diameters below 10 nm. They were accidentally discovered in 2004 by Xu, et al¹ when researching methods to purify carbon nanotubes. Since their discovery they have received much attention from the Materials Science community as a potential alternative to semiconductor quantum dots, especially in biological applications due to their low toxicity. Some of their applications include photocatalysis, solar cells, bioimaging and drug delivery.
