摘要

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.
