dc.description.abstractThis work presents an all-in-one origami paper-based electrochemical platform for simple and inexpensive L-cysteine (Cys) detection using Cys as a monomer for modifying electrode surfaces. The proposed method combines the steps of electropolymerization and detection into a single device to offer a highly convenient method for the end-user. In comparison, the sensitivity toward Cys detection is a significantly increased using this modified electrode. The developed device provided a linear concentration range of 10–800 μM with a limit of detection of 5.5 μM. For application, the device was successfully applied to detect Cys in different food products such as wheat flour, bread, and cake with satisfactory results, yielding excellent intra-day and inter-day relative standard deviations (1.5–4.9%) and recoveries (84.2–110.8%). This discovery is important from the viewpoint of the development of Cys detection in other applications in the future. © 2021
