Abstract

In recent years, paper-based microfluidics has turned into a strong and low-cost analytical tool for detection of diverse analytes of interest. In this work, we develop a pencil-drawn paper-based electrochemical cell (PPEC), with the purpose of fabricating a glucose biosensor. Three different electrode configurations are analyzed as regards their electrochemical behaviour. Biosensor calibration showed a linear and sensitive response for glucose determination. The design presented here is a low-cost, easy to fabricate, lightweight, portable and a green alternative for glucose biosensing.
