One-pot fabrication of nanozyme with 2D/1D heterostructure by in-situ growing MoS2 nanosheets onto single-walled carbon nanotubes with enhanced catalysis for colorimetric detection of glutathione

Recyclable ferroferric oxide@titanium dioxide@molybdenum disulfide with enhanced enzyme-like activity under visible light for effectively inhibiting the growth of drug-resistant bacteria in sewage

“…This phenomenon may be due to the synergistic effect of MoS 2 combined with Fe 3 O 4 @TiO 2 , as well as the interfacial coupling formed in the heterogeneous structure, which enhances the charge transfer and thus the POD-like activity of Fe 3 O 4 @TiO 2 @MoS 2 . 72 We investigated the synergistic relationship between the two activities through the following experiments. As depicted in Fig.…”

N-Rich and Sulfur-Doped Nano Hollow Carbons with High Oxidase-like Activity Prepared Using a Green Template of CaCO3 for Bacteriostasis

“…The inherent limitations of natural enzymes, such as high production costs, short shelf life, and low stability, have led many researchers to seek alternatives. Yan et al first reported in 2007 that magnetic Fe 3 O 4 nanomaterials have enzymatic activity, which triggered a boom in nanoenzyme research. – Inorganic nanomaterials have been reported to have mimetic enzymatic activities such as oxidase-like, peroxidases, catalases (CATs), and superoxide dismutase, and such nanomaterial-based nanoenzymes have been widely used in biosensors, cancer therapy, energy transfer, and bacteriostatic …”

Hierarchical microtubes constructed using Fe-doped MoS2 nanosheets for biosensing applications

“…Molybdenum disulfide (MoS 2 ), one of the classical twodimensional layered materials, has been extensively studied in various areas, especially in enzyme-like catalysis. [12][13][14][15][16][17] MoS 2 NSs have been demonstrated to be promising candidates for enzyme-like catalysis. [18][19][20][21][22] However, the catalytic activity of MoS 2 NSs is discovered from the edges, and the inert basal plane sites and low conductivity of MoS 2 NSs hinder the electron transfer, leading to decreased catalytic performance.…”

“…23 Inspired by this finding, many attempts have been made to synthesize nanostructured MoS 2 with more exposed edge sites to improve the enzyme-like activity. 15,[24][25][26][27] In particular, integrated heteroatom-doping with structural design is proved to be another effective method to enhance the enzyme-like activity of MoS 2 . 28,29 For example, our group combined the coating of polypyrrole (PPy) with noble metal NPs and the transition metal doping strategy to construct tubular MoS 2 -based composites for enhanced performance in enzyme-like catalysis.…”
