Highly sensitive and selective uric acid sensor was fabricated using facile wet-chemically prepared ternary doped ZnO/Ag2O/Co3O4 nanoparticles onto glassy carbon electrode by electrochemical approach, which introduced a prospective and reliable route to the future development of enzyme-free sensor by doped nanomaterials in broad scales.

A facile hydrothermal process was used to prepare nanostructures of ZnO/Yb2O3in alkaline medium, which were applied for efficient chemical sensor development. The sensor fabricated with ZnO/Yb2O3nanostructures may be a promising sensitive chemical sensor for the effective detection of environmental effluents.
