摘要

用纳米金属（金）修饰的介孔薄膜被用于制造超微电极阵列（UMEA）。首次使用探针束偏转（PBD）和循环伏安法研究了超微电极阵列。研究使用[Fe(CN)6]3-/[Fe(CN)6]4-对偶作为氧化还原探针。电化学反应是纳米电极阵列的反应。研究结合孔隙内和溶液-电极界面的质量传输，讨论了扫描速率对电流和 PBD 信号曲线的影响。研究表明，结合 PBD 和 CV 可以更好地了解这种结构复杂的 UMEA 中的质量传输现象。

Probe Beam Deflection Study of Au Nanoparticles Supported Into TiO2 Mesoporous Films

Mesoporous thin films modified with nanoparticles of metal (Au) have been used for the fabrication of an ultra-microelectrode array (UMEA). For the first time, UMEAs were studied using probe beam deflection (PBD) and cyclic voltammetry. The study was carried out using the [Fe(CN)₆]³⁻/[Fe(CN)₆]⁴⁻ couple as a redox probe. The electrochemical response is that of an array of nanoelectrodes. The effects of scan rate on the current and PBD signal profiles are discussed in the context of mass transport within the pores and at the solution-electrode interface. The study suggests that the combination of PBD and CV allows a better understanding of the mass transport phenomena in this type of UMEAs of complex architecture.
