我们提供了一种简单、经济、环保的方法，利用蛋壳膜作为生物模板制备三维分层多孔Co3O4膜。Co3O4纳米纤维相互连接，形成具有大孔和中孔的三维分层多孔膜，更有效地促进了反应物的扩散和电子转移。该传感器可用于葡萄糖的直接电化学非酶检测。灵敏度高(366.03 μ A mM(-1) cm(-2))，响应速度快（3 s），抗干扰性能好，稳定性好。结果表明，三维分层多孔Co3O4薄膜在开发直接电化学非酶葡萄糖生物传感器方面具有很大的应用潜力。(C) 2016 Elsevier B.V.版权所有
We provide a facile, cost-effective and environmentally friendly method to prepare 3D hierarchical porous Co3O4 film by employing eggshell membrane as bio-templates. The Co3O4 nanofibers interconnected with each other to construct a 3D hierarchical porous film with macropores and mesopores, which is more effective in facilitating reactants diffusion and the electron transfer. The developed sensor was applied for direct electrochemical non enzymatic detection of glucose. High sensitivity (366.03 mu A mM(-1) cm(-2)), fast response (3 s), anti-interference performance and excellent stability were achieved. The results demonstrate that the 3D hierarchical porous Co3O4 film have great potential applications in developing direct electrochemical non-enzymatic glucose biosensors. (C) 2016 Elsevier B.V.
