Fabrication of sensitive glutamate biosensor based on vertically aligned CNT nanoelectrode array and investigating the effect of CNTs density on the electrode performance.

本文报道了基于光刻法制备垂直排列碳纳米管纳米电极阵列（VACNT-NEA）并研究碳纳米管密度对电极性能的影响。通过电化学阻抗谱和循环伏安法表征不同扩散机制，所制备阵列呈现由径向扩散主导的稳态电流和S形循环伏安曲线。将VACNT-NEA和高密度VACNTs用作无介质电化学谷氨酸生物传感器，谷氨酸脱氢酶（GLDH）共价连接在碳纳米管尖端...
