Aggregation/dispersion-mediated peroxidase-like activity of MoS2 quantum dots for colorimetric pyrophosphate detectionElectronic supplementary information (ESI) available: Experimental details, additional figures, and PPi assay in real samples. See DOI: 10.1039/c8cc09799b

Peroxidase-like activity of MoS 2 quantum dots can be manipulated by aggregation/dispersion in the presence of Fe 3+ or a mix of Fe 3+ and pyrophosphate (PPi). Based on this finding, a simple and reliable method for colorimetric PPi detection is developed.
