A simple and convenient method for synthesis of GO was reported and converted into rGO via strong reducing reagent.  Electrochemical sensing of Dopamine and Uric Acid was investigated by CV, EIS and SWV.  The modified electrode exhibits good reproducibility, selectivity, sensitivity and stability.

The galvanostatic polymerization of pyrrole is carried out on stainless steel electrodes using p-toluene sulphonic acid. The morphology of the film is studied from Scanning Electron Microscopy (SEM) measurements while the nature of the substrate is analysed using Energy Dispersive X-ray Spectroscopy (EDAX) technique. The electrochemical behaviour is studied using cyclic voltammetry, chargedischarge analysis and impedance spectroscopy. The feasibility of the electrode for supercapacitor applications is investigated. The specific capacitance is estimated as ~10 2 Farads per gram with 10 3 chargedischarge cycles. A plausible equivalent circuit for the system is proposed and the circuit parameters are obtained by non-linear regression analysis.
