A paper-based microfluidic device integrated into a piezoelectric substrate.

A novel, simple and low-cost method for fabricating paper-based microfluidic device was presented. A soldering wire was used for making a template with specific pattern, and transfer printing to a filter paper by help of polydimethylsiloxane (PDMS). The device was mounted on an YX-128° LiNbO₃ piezoelectric substrate. The entire fabrication process could be finished less than one minute without using any complicated equipments. Important parameter in the fabrication of paper-based microfluidic device such as transfer printing time was discussed. To verify the function of the paper-based microfluidic device, color development reactions of starch were implemented. [ABSTRACT FROM AUTHOR]
