A convenient, low cost, and sensitive electrochemical method, based on a disposable graphene nanosheets (GR) and NiO nanoparticles modified carbon screen printed electrode (NiO/GR/SPE), is described for the simultaneous determination of dopamine (DA) and uric acid (UA). The modified electrode exhibited good electrocatalytic properties toward the oxidation of DA and UA. A peak potential difference of 150 mV between DA and UA was large enough to determine DA and UA individually and simultaneously. The anodic peak currents of DA were found to be linear in the concentration range of 1.0–500.0 μM with the detection limit of 3.14×10−7 M.

Graphene has been considered as excellent two dimensional support in recent-times for next-generation graphene-polymer composites towards the development of biosensors. The remarkable properties of polymer and graphene with respect to electrical, mechanical, optical and structural aspect offers an ideal composite support for the development of biosensor. The frontiers of this composites technology is by combining of the polymer and graphene through synergy to achieve the goal of enhanced performance of biosensors with good efficiency and cost effectiveness. Graphene combined with polymer enhances the performance of biosensors in terms of sensitivity, selectivity, response time, and multiplexing capability of biosensors for clinical diagnostics. In this chapter, various methods have been provided to produce the polymer-based graphene composite materials and also discussed the importance of the composite materials to the development of biosensors for clinically important analytes, DNAs, aptamers and immunosensors.
