Introduction to Paper-based Microfluidics

Microfluidics is a rapidly growing field that deals with the behavior, manipulation, and control of fluids at a small-scale level. Paper-based microfluidics is a subset of this technology that utilizes paper as the main substrate for various fluidic applications. Unlike traditional microfluidics, which often requires costly materials and complex fabrication processes, paper-based microfluidics offers a cost-effective and user-friendly alternative.

Understanding Paper-based Microfluidic Devices

Paper-based microfluidic devices are constructed by patterning channels and reservoirs onto a paper substrate. These channels are designed to enable the controlled flow of fluids, allowing for various analytical and diagnostic applications. The capillary action of paper serves as the driving force for fluid flow within these devices.

The design and optimization of paper-based microfluidic devices pose significant challenges due to the complex interaction between fluid flow, analyte transport, and the material properties of the paper. Achieving efficient and reproducible fluid flow rates, minimizing sample loss, and ensuring accurate analyte detection are crucial factors to consider during the design process.
