Dopamine (DOPA) and cortisol is a biomolecules and well-known neurotransmitters in nerve system. In addition, its special binding affinity towards solid surface has been demonstrated in many researches. In this study, in order to construct nanobiotechnology-based electronics, zinc oxide nanoparticles (ZnO NPs) were coupled with dopamine and cortisole, adopted as nanotraps for resistive switching (RS) device. The resistive switching device was fabricated in a structure of metal (Al)/DOPA-ZnO NPs or Cortisol ZnO NPs +PVP (polyvinylphenol)/metal (ITO: Indium Tin Oxide). Resistive switching characteristics between ZnO NPs, DOPA-ZnO NPs and Cortisol ZnO NPs devices were characterized and compared. This RS device can be further developed to form neuromorphic analog device, which can open up a bioelectronic device acting as memory and calculation elements. |
