Abstract
In this study, a resistive switching (RS) memory characteristic of zinc oxide (ZnO) nanoparticles (NPs) multiple layer through a neurotransmitter and its corresponding antibody's specific binding was demonstrated in Al/ZnO NPs/ITO device format. Particularly, a layer-by-layer (LbL) assembly was enabled through a specific immune binding between a stress hormone, cortisol, and its fittable cortisol monoclonal antibody (c-Mab). The assembly formation was accomplished using sequential LbL deposition, which could accomplish alternating self-assembly monolayers (SAMs) of ZnO NPs as the RS active layer. Here, the current-voltage (I-V) curve exhibited disparate nonvolatile RS characteristics depending on sweep polarity showing consecutively evolved hysteresis. In this study, analog-typed RS function of the ZnO NPs LbL device was demonstrated and characterized. (C) 2019 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
