注意事项
超声分散后使用。
Aladdin provides Molybdenum Disulfide (MoS₂) nanoparticles, approximately 100 nm in size, with good photothermal performance and peroxidase-like activity. MoS₂ nanomaterials are a class of two-dimensional photothermal agents. They not only exhibit strong and broad absorption in the near-infrared region but also possess peroxidase-like activity and good biocompatibility. They are widely used in photothermal and catalytic applications for tumor therapy, bacterial infection therapy, and biosensing in biomedical fields.

Under acidic conditions, MoS₂ nanoparticles exhibit POD-like activity, catalyzing H₂O₂ to produce hydroxyl radicals (·OH), which oxidize TMB to form oxidized TMB (oxTMB). oxTMB then combines with TMB to produce a blue substance.
