Nanosized Materials in Amperometric Sensors

Abstract

The use of nanosized materials nowadays constitutes one of the most diffused approach to modify electrode surface when aiming at obtaining efficient amperometric sensors; quite spontaneously, this trend has also involved the field of environmental monitoring. The chapter aims at discussing the properties of nanosized materials, the most widespread strategies for their deposition on the electrode surface as well as the main advantages and limitations of their use in electroanalysis. Metal and carbon nanostructures, and the relevant composite materials, are particularly discussed
