Application of promising carbonaceous materials in electrochemical DNA sensing

The data reported in literature demonstrate that carbon paste electrodes (CPEs) are very suitable for a variety of applications and many works have thus been devoted in the development of new sensitive and selective electrode surfaces based on carbon paste as the electrode material of choice. The application of novel and promising carbonaceous materials, as electrode surfaces, is an issue of gr...

Electrochemical Sensing in Elimination Voltammetry

Elimination voltammetry with linear scan (EVLS) represents the fast and simple improvement of linear-sweep or cyclic voltammetric results. Through the various elimination functions, EVLS offers a new tool not also for better understanding of complex electrochemical processes on the surface of working electrodes, but also for improving the sensitivity of electrochemical measurements. The paper i...

Electrochemical sensing of hepatocyte viability.

We investigated the use of amperometric and chronoamperometric methods with a double mediator system and screen-printed electrodes (SPEs) for the electrochemical sensing of hepatocyte viability. Cell counts were determined based on measuring cellular respiration via interaction of electroactive redox mediators. The oxidation currents of chronoamperometric measurement were proportional to the co...

A Microfluidic Device for Opto-Electrochemical Sensing

A microfluidic device that contains a silica film as optical transducer and electrochemical electrode was used to monitor how ferricyanide ion behaves within nanoporous matrix. This prototype device allows UV-VIS absorption spectroscopy and cyclic voltammetry to be performed at the same time. Significant reducing in leaching of redox molecules proved this device integrated with silica film can ...
