Researchers from Korea's Sungkyunkwan University vertically integrated ZnO nanowires on graphene foams (3D graphene) and used this as electrodes for Parkinson's disease detection - to selectively detect uric acid (UA), dopamine (DA), and ascorbic acid (AA) by a differential pulse voltammetry (DPV) method.
The researchers explain that their electrode is optimized as it has a large surface area with mesoporous 3D graphene structures that facilitate ion diffusion easily. It also features high conductivity from the 3D graphene foam and high selectivity due to the active sites of the ZnO surface.
