摘要
以L-半胱氨酸作为硫的供应体、还原剂、联接剂采用一锅法合成了硫化铜修饰的还原石墨烯纳米复合材料,发现此纳米复合物修饰电极对葡萄糖有良好的电催化效果,并且表现出很高的抗干扰能力、优良的选择性,适用于人体中血清的检测有很好的准确性,有望应用于葡萄糖的无酶传感。
One-pot synthesis of CuS nanoparticle-decorated reduced graphene oxide (CuS/RGO) nano- composites was prepared with the use of L-cysteine, an amino acid, as a reducing agent, sulfur source, and linker to anchor CuS nanoparticles onto the surface of RGO sheets. It was found that the CuS nanoparticles decorated reduced graphene exhibit a remarkable catalytic performance for glucose oxidation. The proposed sensor also showed high anti-interference ability, excellent selectivity and was successfully used for glucose detecting in human serum with good accuracy and satisfactory recovery. It is believed that CuS/RGO composites show good promise for further application on non-enzymatic glucose biosensors.
