In recent years, paper-based microfluidics have turned into a strong and low-cost analytical tool for detection ofdiverse analytes of interest. In this work, we develop a pencil-drawn paper-based electrochemical cell (PPEC), with the purpose offabricating a glucose biosensor. Three different electrode configurations are analyzed as regard their electrochemical behavior.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.
