A novel 3D graphene–carbon nanotube network was constructed on the surface of glassy carbon electrode through a simple and effective electrodeposition approach.
- class="label">•
The prepared 3D interpenetrated graphene-CNT network was successfully used for electrochemical determination of Methotrexate (MTX).
- class="label">•
The improved electrochemical performance is ascribed to the large accessible surafce area of the interpenetrated 3DG network as well as its enhanced electrical conductivity by incorporating CNTs.
- class="label">•
The proposed method can determine MTX in a wide dynamic linear range with a low detection limit.
- class="label">•
The superior properties of the proposed sensing platform make it very suitable for electrochemical determination of MTX in pharmaceutical formulations and clinical preparations.
