In the background of the rapid development of artificial intelligence, big data, IoT, 5G/6G, and other technologies, electrochemical sensors pose higher requirements for high-throughput detection. In this study, we developed a workstation with up to 10 channels, which supports both parallel signal stimulation and online electrochemical analysis functions. The platform was wired to a highly integrated Bluetooth chip used for wireless data transmission and can be visualized on a smartphone. We used this electrochemical test platform with carbon-graphene oxide/screen-printed carbon electrodes (CB-GO/SPCE) for the online analysis of L-tyrosine (Tyr), and the electrochemical performance and stability of the electrodes were examined by differential pulse voltammetry (DPV). The CB-GO-based screen-printed array electrodes with a multichannel electrochemical platform for Tyr detection showed a low detection limit (20 μM), good interference immunity, and 10-day stability in the range of 20-200 μM. This convenient electrochemical analytical device enables high-throughput detection and has good economic benefits that can contribute to the improvement of the accuracy of electrochemical analysis and the popularization of electrochemical detection methods in a wide range of fields.
在人工智能、大数据、物联网、5G/6G等技术快速发展的背景下，电化学传感器对高通量检测提出了更高的要求。在本研究中，我们开发了一种具有多达10个通道的工作站，它支持并行信号刺激和在线电化学分析功能。该平台连接到用于无线数据传输的高度集成蓝牙芯片，并可在智能手机上实现可视化。我们使用这个带有碳-氧化石墨烯/丝网印刷碳电极（CB-GO/SPCE）的电化学测试平台对L-酪氨酸（Tyr）进行在线分析，并通过差分脉冲伏安法（DPV）检测电极的电化学性能和稳定性。基于CB-GO的用于Tyr检测的多通道电化学平台的丝网印刷阵列电极显示出低检测限（20 μM）、良好的抗干扰能力，并且在20-200 μM范围内具有10天的稳定性。这种便捷的电化学分析装置能够实现高通量检测，具有良好的经济效益，有助于提高电化学分析的准确性以及在广泛领域中推广电化学检测方法。
