Herein, a nonenzymatic electrochemical biosensor for glucose detection was developed based on an Au@Pt core–shell nanoparticle-decorated MoS₂ (MoS₂–Au@Pt) nanohybrid. Such designed MoS₂-based nanohybrid possessed the advantages of MoS₂ nanosheets with a large surface area and noble bimetallic nanoparticles with high catalytic ability, making the MoS₂–Au@Pt nanocomposite modified electrode exhibit excellent electrocatalytic activity toward the oxidation of glucose due to their synergistic effect. As expected, the MoS₂-based electrochemical biosensor showed a wide linear response over glucose concentration ranging from 10 μM to 3 mM with a low detection limit of 1.08 μM (S/N = 3). Furthermore, the as-prepared electrochemical biosensor also showed excellent selectivity and stability, which could be employed to determine glucose in real samples with acceptable results. The MoS₂-Au@Pt nanohybrid could be a promising candidate material for the construction of a high performance sensing platform for chemical/biological molecule detection.

MoS ₂ –Au @ Pt纳米杂化物作为电化学非酶葡萄糖检测的传感平台†

在此，基于Au @ Pt核壳纳米粒子修饰的MoS ₂（MoS ₂ -Au @ Pt）纳米杂交体，开发了一种用于葡萄糖检测的非酶电化学生物传感器。这种设计的基于MoS ₂的纳米杂化物具有MoS ₂纳米片的表面积大，贵金属双金属纳米颗粒具有高催化能力的优点，使得MoS ₂ -Au @ Pt纳米复合修饰电极对葡萄糖的氧化具有优异的电催化活性。它们的协同作用。不出所料，MoS ₂的电化学生物传感器在葡萄糖浓度从10μM到3 mM的范围内显示出宽线性响应，检测限低至1.08μM（S / N = 3）。此外，所制备的电化学生物传感器还显示出优异的选择性和稳定性，可用于测定真实样品中的葡萄糖，结果令人满意。MoS ₂ -Au @ Pt纳米杂化物可能是有前途的候选材料，可用于构建用于化学/生物分子检测的高性能传感平台。
