title: One-step ultrasonic synthesis of graphene quantum dots with high quantum yield and their application in sensing alkaline phosphatase.
abstract: With only graphene oxide and KMnO4, the luminescent graphene quantum dots (GQDs) in high quantum yield were prepared by one-step synthesis using ultrasonication, and applied in the label-free, simple and fast fluorescence assay of alkaline phosphatase (ALP).
