Fabrication of Screen-Printed Electrodes Modified by Hydrothermal MnO<sub>2</sub> Microflowers and Carbon for Electrochemical Sensors in Copper Ions Detection

<div>SWASV responses of (a) five MnO<sub>2</sub>/SP-modified SPEs chips and (b) the relevant current density of the anodic stripping peaks. (c) SWASV responses of a MnO<sub>2</sub>/SP-modified SPEs chip measured repeatedly for 10 times, and (d) relevant current density of the anodic stripping peaks. The test solution: 0.1 M NaAc-HAc (pH 5.0) + 10 nM Cu<sup>2+</sup>.</div>
