Abstract

The development of paper analytical devices has been growing mainly due to its features such as simplicity and low cost. Several strategies for the development of these devices have been developed in recent years. This type of electrode is usually manufactured using the application of external reagents on the paper, such as inks or nanoparticles. In this paper we intend to use one of these electrodes, the LS-ePADs (LASER scribed method for the paper-based electrochemical fabrication analytical devices) for the analysis of metal ions. (AU)
