Glucose oxidase (GOx) adsorbed on an ionic liquid-derived polymer containing internally organized columns of Au nanoparticles exhibits direct electron transfer and bioelectrocatalytic properties towards the oxidation of glucose. The cationic poly(ionic liquid) provides an ideal substrate for the electrostatic immobilization of GOx. The encapsulated Au nanoparticles serve to both promote the direct electron transfer with the recessed enzyme redox centers and impart electronic conduction to the composite, allowing it to function as an electrode for electrochemical detection.
葡萄糖氧化酶（GOx）吸附在含有内部组织的金纳米粒子柱的离子液体衍生聚合物上，表现出对葡萄糖氧化的直接电子转移和生物电化学催化性质。阳离子聚（离子液体）为 GOx 的静电固定提供了理想的基质。包裹的金纳米粒子既促进了与凹陷酶氧化还原中心的直接电子转移，又赋予了复合材料电子传导性，使其能够作为电化学检测的电极。
