水杨酸（Salicylic acid， SA）是植物在逆境（特别是生物感染）下释放的主要植物激素。监测植物中SA水平可以为作物病害的早期检测和有效措施的应用提供一条途径，从而提高农业效率。此外，由于其镇痛和抗炎特性，SA在制药和保健行业是一种重要的化学物质。开发一种快速准确的方法来监测人血清中的SA水平，可以对过量和/或误给药的患者产生挽救生命的影响。在这项工作中，我们提出了一种低成本、便携式、可现场部署的电化学SA传感系统，旨在实现上述目标。开发的传感器由即插即用型设备组成，配备了专门设计的高精度传感电子设备和用于稳健数据分析的新程序。所研制的传感器具有良好的线性度、灵敏度和选择性。通过对实际样品中SA含量的准确测量，验证了该传感器的实用性。
Salicylic acid (SA) is a primary phytohormone released in response to stress (particularly biotic infections) in plants. Monitoring SA levels in plants may provide a way for early crop disease detection and application of effective measures, resulting in higher agricultural efficiency. Additionally, SA is an important chemical in the pharmaceutical and healthcare industry due to its analgesic and anti-inflammatory properties. Developing a fast and accurate way for monitoring SA levels in human serum can have a life-saving impact for patients suffering from overdosing and/or mis-dosing. In this work, we present a low-cost, portable, and field-deployable electrochemical SA sensing system aimed towards achieving the above-mentioned goals. The developed sensor consists of a plug-and-play type device equipped with specially designed high accuracy sensing electronics and a novel procedure for robust data analysis. The developed sensor exhibits excellent linearity and sensitivity and selectivity. The practical applicability of the developed sensor was also demonstrated by measuring SA levels in real samples with good accuracy.
