Paper-based analytical devices offer advantages such as low cost, convenient production, and rapid output, with enclosed channel designs providing protection for device contents. However, the superior properties of enclosed device designs are often overlooked, highlighting the need to fill this gap in the field with further discussion and research.
Paper-based analytical devices possess desirable properties such as low cost, convenient production, and rapid output. These advantages over conventional analytical devices have attracted tremendous attention in recent years, and an abundance of fabrication techniques have been achieved with different designs. Related approaches are adopted by scientists and engineers from different research fields to create practical devices tailored for various applications. Among a diverse selection of strategies, paperbased analytical devices featuring enclosed channels can protect its contents from environmental harm, which is helpful in designing paper-based devices aimed toward practical use. However, superior properties of enclosed device designs have often been neglected when a paper-based platform is selected, and related discussion is still lacking in the field. To fill this empty space in the relevant literature, important issues are highlighted and recent research achievements are included in this article, which should have implication for scientists interested in sensing technology, analytical chemistry, material science, and miniaturized devices. For the convenience of reader's understanding, this article provides a general introduction to the basic properties and concepts of paper-based analytical devices. Firstly, commonly used fabrication strategies and detection methods are mentioned, with an in-depth emphasis on paper-based devices with enclosed channels, including breakthroughs in device types, thoughts on novel fabrication, and practical application examples. Subsequently, other important topics related to enclosed paper-based device design are summarized, and future challenges and opportunities in the field are also discussed. (C) 2020 Elsevier B.V.
