Article Synopsis
- * This electrode demonstrated high sensitivity (4.36 μA μM) and a low limit of detection (0.04 μM), making it effective for detecting dopamine levels.
- * The sensor showed excellent selectivity against uric acid interference, along with good repeatability and stability, indicating its potential applications in medical and health-related fields.
An electrochemical sensor is described for simultaneous voltammetric determination of dopamine (DA) and uric acid (UA). It is based on the use of a nanomaterial composed of gold nanoparticles and 3-dimensional graphene (Au NP@3D GR). The 3D GR was prepared by chemical vapor deposition using nickel nanoparticles as the template at a temperature of around 900 °C.
