- •
Graphene-pyrroloquinoline quinone (Gr-PQQ) composite was formed by simple adsorption.
- •
Gr-PQQ film modified electrode was highly sensitive to electrooxidation of NADH.
- •
Gr and PQQ show synergistic effect on enhanced detection performances.
- •
The sensors can successfully determine NADH in human serum samples.
