Electrode modification using porous layers. Maximising the analytical response by choosing the most suitable voltammetry: Differential Pulse vs Square Wave vs Linear sweep voltammetry

Abstract:

The analytical benefits obtained from electrode modification with conductive porous layers, a common practice in the development of electrochemical (bio)sensors, are examined for the main electroanalytical techniques: differential pulse, square wave and linear sweep voltammetry. The electrochemical response is analyzed in terms of the effect of the modification on the electrode kinetics and on the diffusion transport of the target species. With respect to the former, the gain in the current p...
