  • Title: High peroxidase-mimicking activity of gold@platinum bimetallic nanoparticle-supported molybdenum disulfide nanohybrids for the selective colorimetric analysis of cysteine.
    Author: Wan L, Wu L, Su S, Zhu D, Chao J, Wang L.
    Journal: Chem Commun (Camb); 2020 Oct 21; 56(82):12351-12354. PubMed ID: 32930293.
    Abstract:
    Herein, gold@platinum (Au@Pt) bimetallic nanoparticles with high catalytic ability were in situ decorated onto a molybdenum disulfide (MoS2) surface to obtain nanocomposites (MoS2-Au@Pt) with high peroxidase-mimicking activity, which were used to construct a colorimetric sensor for cysteine (Cys) detection. Interestingly, this sensor can efficiently distinguish Cys from homocysteine (Hcy), glutathione (GSH) and 19 other amino acids with high sensitivity. As expected, the colorimetric sensor can determine the Cys content in Cys supplement tablets due to its high stability and repeatability. Finally, the detection mechanism was studied.
