Switch-on fluorescent strategy based on N and S co-doped graphene quantum dots (N-S/GQDs) for monitoring pyrophosphate ions in synovial fluid of arthritis patients

This work reports a facile and effective approach for preparing graphene quantum dots co-doped with nitrogen and sulfur (N-S/GQDs). The proposed method comprised pyrolysis of citric acid with glutathione and dialysis treatment. The fabricated N-S/GQDs exhibited blue luminescence and a high fluoresce...
