the electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (mwcnts) is presented. cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (ppo). a redox couple with an anodic and counterpart cathodic peak is obtained. the influence of various parameters such as ph, scan rat...

An analytical method has been described for the determination of mercury using a carbon paste electrode. Conditions for the preparation of the carbon paste electrode were optimized for low background current in order to use it for the determination of ultra trace levels of mercury. The carbon paste electrode was found to be a good electrode material for the determination of mercury. The optimiz...

This mini review describes the results regarding the voltammetric determination of micromolar, submicromolar and nanomolar concentrations of various fluoroquinolones antibacterial agents using both traditional hanging mercury drop electrode, carbon paste electrode, glassy carbon paste electrode and chemically modified electrodes. We concentrate on the interaction of quinolones with DNA in solut...

This article is focused on the determination of lidocaine hydrochloride as a local anaesthetic drug. A potentiometric method based on modified screen-printed and modified carbon paste ion-selective electrodes was described for the determination of lidocaine hydrochloride in different pharmaceutical preparations and biological fluids (urine and serum). It was based on potentiometric titration of...

Article history: Received 7 December 2013 Accepted 29 January 2014 Available online 6 February 2014 The electrical conduction and dielectric (capacitive) properties of electrolyte-filled carbon paste electrochemical electrodes are reported, with the carbon, electrolyte (15% H2SO4), carbon–electrolyte interface and carbon–contact(metal) interface contributions fully decoupled for the first time....

The unique properties of graphene, such as the high elasticity, mechanical strength, thermal conductivity, very high electrical conductivity and transparency, make them it an interesting material for stretchable electronic applications. In the work presented herein, the authors used graphene and carbon nanotubes to introduce chemical sensing properties into textile materials by means of a scree...
