Paper-based electrochemical sensors (PESs) have been evidenced as analytical strategies for employing simple, low-cost, portable and disposable sensing platforms that can be used in many application areas. Recently, PESs have gained extensive attention because of their advantages of advanced sensitivity and selectivity during detection provided by electrochemistry, compared with microfluidic paper-based analytical devices (μPADs) that still lack these advantages. Also, it can be expected that PESs can better meet current user demands, making them a stand-out analytical tool because of their capability for multiple analyte detection and their compatibility in a variety of application areas, like clinical diagnosis, environmental monitoring and food quality control. Herein, in this mini review, we present an overview of recent developments in PESs over the last decade, focusing on existing fabrication techniques and application areas, specifically in relation to clinical diagnostics, food quality control and environmental monitoring, where simple and portable analytical devices are greatly needed. A summary and future outlooks for PESs are also discussed.
纸质电化学传感器（PESs）已被证明是一种分析策略，可用于构建简单、低成本、便携且一次性使用的传感平台，这些平台可应用于许多领域。最近，与仍缺乏这些优势的微流控纸质分析装置（μPADs）相比，PESs因其在检测过程中具有电化学提供的高灵敏度和选择性优势而受到广泛关注。此外，可以预期PESs能够更好地满足当前用户需求，因其具备多分析物检测能力以及在临床诊断、环境监测和食品质量控制等多种应用领域的兼容性，使其成为一种出色的分析工具。在此，在本综述中，我们概述了过去十年中PESs的最新进展，重点关注现有的制造技术和应用领域，特别是与临床诊断、食品质量控制和环境监测相关的领域，在这些领域中，对简单便携的分析装置有极大需求。还讨论了PESs的总结和未来展望。
