摘要

背景扫描电化学显微镜(SECM)是一种扫描探针技术,通过记录探针移动时引发的法拉第电流变化,获取表面形貌和电化学信息。结果在这项工作中,通过一种简单而通用的策略,即真空拉伸插入铂丝(金丝、碳纤维等)的玻璃毛细管,然后快速加热密封和抛光,制备了具有高度可重复性几何形状的柔性圆盘超微电极(UME)。根据光学和电化学表征,制备的 UMEs 具有良好的几何形状,RG 值在 1.7 到 2 之间。此外,由于具有出色的柔韧性,制备的 UME 在针尖与样品碰撞时的损坏率极低,接触扫描后在苹果皮上产生的痕迹不可见,远远优于传统的 UME,在生物相关领域具有广阔的应用前景。

Flexible disk ultramicroelectrode: facile preparation and high-resolution scanning electrochemical microscopy imaging

Background

Scanning electrochemical microscopy (SECM) is a kind of scanning probe technology that enables the obtainment of surface morphology and electrochemical information by recording changes in Faraday current triggered by the movement of probe.

Results

In this work, flexible disk ultramicroelectrode (UME) with highly repeatable geometry are fabricated through a simple and universal strategy that involves vacuum pulling the glass capillaries inserted with platinum wire (gold wire, carbon fiber, etc.), followed by a rapidly heated sealing and polishing process. Based on the optical and electrochemical characterization, the as-prepared UMEs possess favorable geometric shape with a small RG value from 1.7 to 2. Consequently, when applied as probe components for SECM imaging on interdigital electrodes, it can achieve excellent spatial resolution and high sensitivity at short working distances. Moreover, due to the outstanding flexibility, the as-prepared UMEs can be minimally damaged arising from tip-sample collision and produce invisible trace on apple peel after the contact scanning, which is far superior to the traditional UME and suggests the application potential in bio-related fields.

Significance

Our work will inspire the application of flexible UMEs as probe components in SECM, and consequently promote the widespread use of SECM with reduced collision threshold and low operational difficulty.
