We propose a method for the electrochemical identification of plants by embedding leaf tissue into graphene deposited on a screen-printed electrode (SPE). The embedding process significantly enhanced the electrochemical signals, which made the SPE sufficiently sensitive to record information about electro-active compounds in plants. In this work, five Lycoris herbs have been used as examples to evaluate the feasibility of the proposed technique. Multidimensional pattern recognition was successfully established for plant identification. In addition, the recorded “electrochemical fingerprints” provided valuable taxonomic information, demonstrating the enormous potential of the technique for plant chemotaxonomy.

我们提出了一种通过将叶片组织嵌入丝网印刷电极（SPE）上沉积的石墨烯中来进行植物电化学鉴定的方法。嵌入过程显着增强了电化学信号，这使SPE足够灵敏，可以记录有关植物中电活性化合物的信息。在这项工作中，以5个石蒜草药为例，评估了该技术的可行性。多维模式识别已成功建立，可用于植物识别。此外，记录的“电化学指纹”还提供了有价值的分类学信息，证明了该技术在植物化学分类学方面的巨大潜力。
