Abstract

Electrochemical sensors are increasingly garnering attention as valuable tools for point-of-care (POC) testing due to their low costs, high sensitivities, and ease of miniaturization. Graphene-based materials, renowned for their tunable electrical conductivity, high specific surface areas, versatile functionality, and biocompatibility; are highly suited for the fabrication of electrochemical sensors with heightened sensitivities. Non-contact, maskless, direct writing methods allow the rapid, large-scale production of graphene electrodes with high design flexibility. Researchers globally are advancing graphene electrode production, aiming for smaller, faster, and more efficient sensors. This review provides a comprehensive overview of recent advances on the direct writing of graphene electrodes for electrochemical sensing applications. It covers the basics of direct writing techniques, the advancements in graphene ink/precursor preparation, structural design, and device integration, with a focus on POC platforms.

直接写入石墨烯电极用于护理点电化学传感应用
电化学传感器因其低成本、高灵敏度和易于微型化等特点,正日益受到人们的关注,成为进行床旁(POC)检测的重要工具。石墨烯基材料以其可调导电性、高比表面积、多功能性和生物兼容性而闻名,非常适合制造灵敏度更高的电化学传感器。通过非接触、无掩模、直接写入的方法,可以快速、大规模地生产具有高度设计灵活性的石墨烯电极。全球的研究人员正在推进石墨烯电极的生产,目标是制造出更小、更快、更高效的传感器。本综述全面概述了直接写入石墨烯电极用于电化学传感应用的最新进展。它涵盖了直接写入技术的基础知识、石墨烯墨水/前驱体制备的进展、结构设计和器件集成,重点关注 POC 平台。
