Fabrication of Paper-based Microfluidics by One-step Hot Microembossing

Abstract

In recent years microfluidic paper-based analytical device (?PAD) has been receiving attention because it is simple inexpensive and power-free for low-cost chemical biological and environmental detection Moreover paper is lightweight easy to stack store and transport biodegradable biocompatible good for colorimetric tests flammable for easy disposal of used paper-based diagnostic devices by incineration and can be chemically modified Different methods have been demonstrated to fabricate ?PADs such as solid wax printing craft cutting photolithography etc In this study we proposed and demonstrated one-step hot microembossing to fabricate ?PADs The processing parameters like temperature embossing pressure and embossing time were systematically studied The results showed that the temperature and embossing time played important roles in fabrication of ?PADs Heavy metal detection was conducted to verify the performance of ?PADs as fabricated Fabrication of ?PADs can be completed within 10 seconds
