Abstract

There is a great interest in environmental monitoring of chemicals known as endocrine disrupters (DE) from industrial and human waste that may interfere with the endocrine system of humans and other animals. However, the monitoring of these substances is generally based on chromatographic methods. In this sense, the development of Sensor materials for monitoring these substances presents several advantages such as lower cost and time as well as offering the possibility of in-situ monitoring. Conducting polymer-based materials (CP 's) and carbon nanotubes (CNT 's) are being increasingly used in the development of sensors. The CP's main characteristic is its electrical conductivity that can be regulated in wide range, through interactions with electron donors and receptors, which makes them attractive as active transducers while the CNT's have the ability to promote electron transfer reactions, increasing the reaction speeds and decreasing the oxidation potentials. Thus, composites based on CP's and CNT's have been developed and showed synergistic properties such as increasing the sensitivity and selectivity in relation to its separated materials. In this project, self-assembled films based on composites of CP´s and CNT's will be produced and evaluated in determination of DE substances such as pesticides, pharmaceuticals and hormones in marine environment.
