New conductive devices for application in electrochemical sensing and biosensing

Abstract

The electrochemical sensors and biosensors can facilitate the resolution of modern problems relatively quickly. The need for new methodologies and improvements in disease detection processes, aiming for accuracy and speed, leads to the development of new technologies. Therefore, analysis of diseases that would take weeks can be carried out in a few hours, with high accuracy and reliability. Based on screen-printing and electrochemical techniques, we aim to develop disposable electrodes with relative low cost by using environmentally friendly materials. In this context, the objective of this project is a proposal of new electrochemical sensors and biosensors, by using disposables, versatiles and low cost platforms such as PET and paper. In a first step, it will prepared conductive inks with polym,ers and carbon materials. In a second moment, electrodes will be prepared from the electro-spinning technique. As a form of application, we propose the use of these disposable electrodes in the electrochemical detection of biomarkers related to Alzheimer's and Parkinson's diseases. It is expected to obtain devices with high sensitivity, wide linear ranges, stable, with low detection limits and robust. (AU)
