建立了一种原位合成高质量金纳米颗粒包裹的多层石墨烯（AuNP-FLG）纳米杂化材料的新方法。采用化学气相沉积法成功制备了AuNP-FLG纳米杂化物，并将其作为电催化剂用于高灵敏度的非酶葡萄糖传感器。该电极对葡萄糖的氧化具有良好的电催化活性，在0.0 V的工作电位下，线性检测范围为6 μM-28.5 mM，检测限为1 μM，灵敏度为0.195 μA mM−1cm− 2。此外，电极还表现出长期稳定性（两周后保留率为95.4%），抗坏血酸、4-乙酰氨基苯酚和尿酸的干扰可以忽略不计。结果表明，金纳米颗粒-FLG电极在非酶葡萄糖传感器的开发中具有良好的应用前景。
A novel route for in-situ synthesis of high-quality gold nanoparticles-encapsulated few layered graphene (AuNP-FLG) nanohybrids has been established. The AuNP-FLG nanohybrids were successfully synthesized by chemical vapor deposition technique and used as an electrocatalyst for high sensitive non-enzymatic glucose sensors. The amperometric response of the AuNP-FLG based electrode achieved an excellent electrocatalytic activity towards glucose oxidation with a wide linear detection range of 6 μM–28.5 mM, low detection limit of 1 μM and a sensitivity of 0.195 μA mM−1cm−2at operating potential of 0.0 V. Furthermore, the electrode also showed long-term stability (retention of 95.4% after two week) with negligible interference from ascorbic acid, 4-acetamidophenol and uric acid. The results implied that AuNP-FLG could be a promising electrode material in the development of non-enzymatic glucose sensors.
