Abstract

A method is proposed for estimating the porosity of paper by comparing the electric current passing through a wax-printed channel patterned on the paper surface with that passing through a hollow PDMS channel. To ensure the accuracy of the estimation results, the paper channel is sandwiched between two flat polydimethylsiloxane (PDMS) plates in order to minimize evaporation losses and to emulate the surface condition of the hollow PDMS channel used for reference purposes, a good agreement is observed between the estimated values of the paper porosity and the porosity values determined from the basis weight and thickness data provided by the paper manufacturer. The proposed method provides a low-cost and effective means of evaluating candidate materials for microfluidic paperbased analytical devices (μPADs).
