A novel sensitive Cu(II) and Cd(II) nanosensor platform: Graphene oxide terminated p-aminophenyl modified glassy carbon surface

- We electrochemically prepared sensor based on graphene oxide.
- The prepared electrode was characterized by using various techniques.
- The proposed nanosensor showed good stability, selectivity and high sensitivity.
- The proposed nanosensor electrode was used for the analysis of Cd(II) and Cu(II).
