The carbon dots(CDs),a new member of carbon nanomaterials,have gained tremendous attention in application for bioimaging,1 drug delivery,photocatalysis,sensing of metal cations and biological molecules,2 and light-emitting devices,owing to their remarkable advances in high resistance to photobleaching,low toxicity,high sensitivity,good biocompatibility,and robust chemical inertness.In this work,we have developed a green,simple,and low-cost hydrothermal method using human hair as the precursor to fabricate sulfur-doped and nitrogen-rich carbon dots.
