我们描述了一种基于移动微量移液器和微电极阵列组合的电化学测量和合成方法，我们将其称为阵列微池方法（AMCM）。 AMCM 能够对微电极阵列 (MEA) 内的单个电极进行寻址，并提供简单、低成本的格式来实现多功能电化学测量。在AMCM中，可移动微量移液器（内径为50μm）尖端的液滴充当电化学电池，其中电极区域由阵列的微电极限定。我们还报告了非常适合 AMCM 并由热解光刻胶薄膜 (PPF) 制成的碳 MEA。通过 AMCM、标准宏观电化学方法和有限元建模对标称电极直径为 5.5 μm 的 PPF-MEA 进行表征。通过测量单个 Pt 微粒和形状控制的 Pt 纳米颗粒的电沉积，证明了 AMCM 的多功能性。
We describe a method for electrochemical measurement and synthesis based on the combination of a mobile micropipette and a microelectrode array, which we term the array microcell method (AMCM). AMCM has the ability to address single electrodes within a microelectrode array (MEA) and provides a simple, low-cost format to enable versatile electrochemical measurements. In AMCM, a droplet at the tip of a movable micropipette (inner diameter of 50 μm) functions as an electrochemical cell, in which the electrode area is defined by a microelectrode of the array. We also report carbon MEAs that are well suited for AMCM and are fabricated from pyrolyzed photoresist films (PPFs). PPF-MEAs with nominal electrode diameters of 5.5 μm are characterized by AMCM, standard macroscale electrochemical methods, and finite element modeling. The versatility of AMCM is demonstrated by measurement of single Pt microparticles and by electrodeposition of shapecontrolled Pt nanoparticles.
