Development of a new paper-based test system using electrochemical reactions — Marc Riedel¹, •Oliver Nagel², Werner Wirges², Robert Niedl², Fred Lisdat¹, and Carsten Beta³ — ¹Technische Hochschule Wildau — ²Universität Potsdam — ³Diamond Inventics

Paper-based sensors have reached a wide popularity in research and industry. Such systems are low cost in production and simple to fabricate. Furthermore, the benefit in analysis speed and availability made them attractive and easy to use as analytical tools. Paper is available in a wide range of thicknesses, it is biodegradable, and environmentally friendly. The hydrophilicity and porosity of the paper provide a natural substrate for the fabrication of microfluidic channels and can be operated without an external power source for fluid control. It is possible to easily print, coat, and link chemical reagents or (bio)molecules to the paper surface. This work will show a new paper-based test system consisting of a carbon and a silver electrode printed on the paper to detect electrochemical reactions on the chip. To test the µPAD (microfluidic paperbased analytical device), a peroxidase/ferrocene redox system was used for amperometric measurements.
