Enzyme Chemotaxis on Paper-based Devices
Analytical Sciences, 2018 Microfluidics has served as a technology for the design and development of a myriad of devices owing to their reduced reagent consumption rate and short sampling-to-result time. Chemotaxis is the movement of materials, particularly biological species, in response to the influence of chemical stimulation.

Flexible Graphite-on-Paper Piezoresistive Sensors
Sensors, 2012 We demonstrate novel graphite-on-paper piezoresistive devices. The graphite was used as sensing component. The fabrication process can be finished in a short time with simple tools (e.g., a scissor and a pencil).

Predicting Dimensions in Microfluidic Paper Based Analytical Devices
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.

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
