▎ 摘　　要

NOVELTY - Production of graphene quantum dots involves manipulating and controlling flow of an aqueous suspension of graphite flakes through micro-channels. USE - Production of graphene quantum dots e.g. aqueous solution of graphene quantum dots (claimed). Uses include but are not limited to photovoltaics, bio-imaging, LED, sensors, cellular imaging, molecular tracking in live cells, bio-sensing and drug delivery. ADVANTAGE - The method is simple, economical and environmentally-friendly. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of the process for producing graphene quantum dots. Aqueous suspension preparing process (210) Aqueous suspension injecting process (215) Aqueous suspension circulating process (220) Surfactant adding process (230) Aqueous solution filtering process (240)
