Sulfur doped graphene quantum dots as a potential sensitive fluorescent probe for the detection of quercetin

•Design and synthesis of a novel fluorescent sensing probe.•Quenching in fluorescence of SGQDs by quercetin was explained through the inner filter effect (IFE).•IFE-based fluorescent probe was developed to detect quercetin in real-time red wine samples.•Fluorescent probe exhibited virtues of rapidit...
