This study focus on developing a [CuO-Pencil Electrode using Jaft] (JCPE, Jaft CuO Pencil Electrode) using Copper(II) Oxide (CuO) nanoparticles synthesized from acorns and graphite pencil lead electrodes to detect dopamine, a neurotransmitter contained in the body. CuOsynthesized using acorns is used because it is judged that it will be more eco-friendly than the existing CuO synthesis method using strong base materials. The CuO we made was confirmed through X-ray Diffraction,Scanning Electron Microscope, Fourier transform infrared, Energy-dispersive X-ray spectroscopy. In addition, through Electrochemical Impedance Spectroscopy, it is confirmed that it will be advantageous for detection when the CuO we use is attached to the electrode. The sensors we manufactured have a linear range of 250 to 1750μM, a sensitivity of -0.03891μA/μM, and a R-square is 0.99225.
