| 英文摘要: |
| The study used electrochemical deposition to prepare reduced graphene oxide and gold nanoparticles on the surface of screen-printed carbon electrodes to,which constructed a graphene electrochemical sensor for SARS-Cov-2. The successful modification of the nanocomposites on the electrode surface was characterized and analyzed by scanning electron microscopy (SEM) and corresponding electrochemical methods. The performance of the sensor was also examined by differential pulse voltammetry, and the electrochemical sensor constructed in this experiment has good sensitivity, which has a detection limit of 1.667×10-7 mol/L and a linear range of 10-10-10-6 mol/L |
