Another novel method for creating movable valves on paper-based microfluidic devices has been described in this paper. The method uses hollow rivets as the holding center to control the movement of the paper channel, resulting in its connection or disconnection, allowing manipulation of capillary-driven fluids. The process is relatively simple, versatile, and compatible with microfluidic paper-based analytical devices (μPADs) of varying levels of complexity. What is particularly noteworthy about the movable valve is that it can be controlled conveniently and freely without the need for timing settings, making it user-friendly even for untrained users to perform complex multistep operations. The performance of the movable valve has been validated through several different designs of μPADs that yielded satisfactory results. The technique has also been applied to proof-of-concept enzyme-linked immunosorbent assay experiments, successfully analyzing carcinoembryonic antigen samples with good sensitivity and reproducibility. The authors hope that this method will open new avenues for easily adoptable and widely available fabrication of paper-based valves in μPADs, with potential point-of-care applications in the future. The hollow-rivet-assisted movable valve presented in this work offers a versatile, one-step fabrication, cost-effective, and easily operable method for μPADs. Its ability to move flexibly in space enables its reusability with good repeatability. The RAM valve's performance was assessed through several different designs of μPADs, demonstrating good results. The authors believe that movable valves offer excellent opportunities for performing complex multistep operations such as point-of-care testing and on-field detection, among other biochemical assays, without the need for complicated fabrication processes.
