A biocompatible silk fibroin-based carbon quantum dot (SF-CQD) is first synthesized under microwave irradiation for a short time. This fast and environmentally safe technique produce well-defined nanosized SF-CQDs. The SF-CQDs have good crystallinity, a strong emission peak in the blue-color region, high quantum yield, and the potential for modification with various functional groups on the surface. These SF-CQDs demonstrate stable emission, good water dispersity, low toxicity, and good biocompatibility. These properties show the great potential of these SF-CQDs for use in biomedical applications including bioimaging, biosensing, and drug delivery systems.
