Paper-based microfluidic devices by asymmetric calendaring [PDF]

open access: yesBiomicrofluidics, 2017
We report a simple, efficient, one-step, affordable method to produce open-channel paper-based microfluidic channels. One surface of a sheet of paper is selectively calendared, with concomitant hydrophobization, to create the microfluidic channel. Our method involves asymmetric mechanical modification of a paper surface using a rolling ball (ball-point

Predicting Dimensions in Microfluidic Paper Based Analytical Devices [PDF]

open access: yesSensors, 2020
The main problem for the expansion of the use of microfluidic paper-based analytical devices and, thus, their mass production is their inherent lack of fluid flow control due to its uncontrolled fabrication protocols. To address this issue, the first step is the generation of uniform and reliable microfluidic channels.
