Electrochemical Sensors Based on Nanostructured Materials

Abstract

Nanostructured materials became in the past years the materials of choice for the design of new electrochemical sensors. Enhanced electrocatalytic properties obtained due to the increase of active surface and the electrocatalytic activity of the nanostructured material were recorded for the amperometric sensors. Stochastic sensors based on channel conductivity improved the quality and reliability of measurements especially when used in biomedical analysis. Design of sensors based on graphene, carbon nanotube, and carbon nanopowder will be discussed. Surface analysis is essential in the evaluation of the active area of the sensors. The most important applications of the sensors based on nanostructured materials will be shown.
