Flow control in paper-based microfluidic channel by using hydrophobic tape barrier on the paper surface

Paper-based microfluidics offers a simple, cost-effective, and versatile platform for fluid manipulation analysis. Despite significant advancements in paper fluidics, the flow control channel remains challenging task. In this regard, we have developed delay using rectangular tape patterns on surface. We investigated effect of hydrophobic barriers with varying widths. The designing cutting was performed by CO 2 laser machine CorelDraw software. Once cut, were attached to surface then passed through roller press proper adhesion pattern onto paper’s From experiments, observed that increasing width tape, also increased. caused resistance flowing fluid. Due resistance, velocity reduced, time believe our novel approach will provide an alternative method paper-based microfluidic devices can be utilized various food quality sensors lateral devices.
