Nano-Modified Screen-Printed Electrodes for the Determination of Organic Pollutants

Abstract

This paper deals with low-cost sensors to detect the presence of organic pollutants, based on the voltammetric response of Screen Printed Electrodes (SPE). Modified SPEs are here proposed, by using graphene nanoplatelets that represent a low cost version of graphene, characterized by an easier and more scalable production compared to pure graphene. Improved sensing performance are experimentally observed with these surface modifications to the detection of an aromatic organic compound.
