Abstract
A dopamine (DA) sensor includes a glassy carbon electrode including an indium oxide doped zinc oxide (In2O3-doped ZnO) decorated mesoporous carbon (In2O3·ZnO@MC) nanocomposite material. The In2O3·ZnO@MC includes aggregates of spherical In2O3 nanoparticles (NPs) and cubic ZnO NPs dispersed on the surface of the mesoporous carbon.
