▎ 摘　　要

NOVELTY - Preparing porous graphene quantum dots involves dissolving chitosan in aqueous acetic acid solution to obtain aqueous chitosan acetate solution, and adding graphite to aqueous chitosan acetate solution. The mixture is stirred to obtain a solution. The obtained solution is ultrasonically processed in an ultrasonic cleaner. The mixture is centrifuged to obtain a porous graphene quantum dots. USE - Method for preparing porous graphene quantum dots (claimed) used for cell imaging.
