Paper-based microfluidic devices by asymmetric calendaring [PDF]
Biomicrofluidics, 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]
Sensors, 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.

Paper-Based Microfluidics Immunoassay for Detection of Canine Distemper Virus
Brazilian Archives of Biology and Technology, 2018 Paper-based devices present low-cost and are versatile, making them very attractive for clinical analysis. To manufacture those devices wax patterns are printed on paper surface and upon heating the wax permeates through the entire thickness of the paper,
