“…[38][39][40] Patterned paper is ideal for low-cost, portable, and technically simple multiplexed bioassays. [41][42][43][44] Paper-based microfluidics offer many unique advantages over conventional microfluidics in terms of unpowered fluid transport via capillary action, high surface area to volume ratio for chemical reactions and assays, and the ability to store reagents in an active form within the fiber network. 45 With the advantages mentioned above, paper has become an attractive substrate material for in situ sweat detection, which makes it a promising starting point for a "lab on paper".…”

“…Kirigami was shown via cut-and-paste protocol to fabricate 3D microfluidic paperbased analytical devices for on-site quantitative assay applications. [53] Reaction channels were cut from filter paper and assembled on silanized, superhydrophobic paper. Device layers were then assembled using a chemically-inert adhesive spray to achieve efficient liquid handling at low cost.…”

Mechanically flexible and conformable materials and integrated devices have found diverse applications in personalized healthcare as diagnostics and therapeutics, tissue engineering and regenerative medicine constructs, surgical tools, secure systems, and assistive technologies. In order to impart optimal mechanical properties to the (bio)materials used in these applications, various strategies have been explored—from composites to structural engineering. In recent years, geometric cuts inspired by the art of paper‐cutting, referred to as kirigami, have provided innovative opportunities for conferring precise mechanical properties via material removal. Kirigami‐based approaches have been used for device design in areas ranging from soft bioelectronics to energy storage. In this review, the principles of kirigami‐inspired engineering specifically for biomedical applications are discussed. Factors pertinent to their design, including cut geometry, materials, and fabrication, and the effect these parameters have on their properties and configurations are covered. Examples of kirigami designs in healthcare are presented, such as, various form factors of sensors (on skin, wearable), implantable devices, therapeutics, surgical procedures, and cellular scaffolds for regenerative medicine. Finally, the challenges and future scope for the successful translation of these biodesign concepts to broader deployment are discussed.

Point-of-care testing (POCT), as a portable and user-friendly technology, can obtain accurate test results immediately at the sampling point. Nowadays, microfluidic paper-based analysis devices (μPads) have attracted the eye of the public and accelerated the development of POCT. A variety of detection methods are combined with μPads to realize precise, rapid and sensitive POCT. This article mainly introduced the development of electrochemistry and optical detection methods on μPads for POCT and their applications on disease analysis, environmental monitoring and food control in the past 5 years. Finally, the challenges and future development prospects of μPads for POCT were discussed.
