Visual detection of blood glucose based on peroxidase-like activity of WS2 nanosheets

Prussian blue nanocubes peroxidase mimetic-based colorimetric assay for screening acetylcholinesterase activity and its inhibitor

“…Very recently, nanoscaled peroxidase mimics have received great attention since the first Fe 3 O 4 nanoparticles-based peroxidase mimetic was reported [25]. A variety of nanomaterials, such as carbon nanomaterials [26][27][28][29], BSA-stabilized Au clusters [30], Au NPs [31], CuO nanoparticles [32], Co 3 O 4 nanoparticles [33], MoS 2 nanosheets [34], carbon nitride nanosheets [35], WS 2 nanosheets [36], TiO 2 nanotube arrays [37], have been demonstrated to possess peroxidase-like activity.…”

Carbon coated magnetite nanoparticles with improved water-dispersion and peroxidase-like activity for colorimetric sensing of glucose

“…In compared with natural enzymes, enzyme-like namomaterials exhibit the advantages of easy preparation, great resistance to harsh chemical environment and tunable catalytic activity [5]. As such, a variety of nanomaterials including Fe 3 O 4 nanoparticles (NPs) [2], carbon dots [6], carbon nanotubes [7], graphene dots [8], and WS 2 nanosheets [9] have been evaluated as enzymatic mimics for the detection of glucose. Nevertheless, laborious procedures are often required for the preparation of these nanomaterials.…”

The use of tungsten disulfide dots as highly selective, fluorescent probes for analysis of nitrofurazone

“…These methods include liquid exfoliation [8,9], hydrothermal synthesis [10,11], pyrolysis [12], chemical vapor deposition [13] and electrochemical Li-intercalation [14]. TMDCs have a wide variety of mechanical and electronic applications with semiconductors of MoS 2 [15,16], MoSe 2 [17,18], WS 2 [19,20] and WSe 2 [21,22]. In particular, the WS 2 material consists of 2D covalently bonded S-W-S layers separated by a van der Waals gap.…”
