摘要

Abstract In this work, a simple procedure for construction of disposable electrochemical paper‐based analytical devices (ePADs) by screen‐printing using low‐cost materials and a home craft electronic printer is proposed. The devices were constructed using liner paper as a substrate and carbon ink prepared with graphite powder and wood glue. The ePAD was evaluated as an electrochemical sensor and biosensor. The proposed conductive carbon‐based ink can be easily prepared and is an eco‐friendly and non‐toxic material. The developed ePAD was simple to produce and can be used as a low‐cost electrochemical sensor, at less than US $0.20 per device.
