We present a simple, low-cost and scalable method for fabricating externally pressurized paper-based microfluidic devices. Known as microfluidic pressure in paper (µPiP), devices fabricated by this technique are capable of sustaining a pressure gradient for use in precise liquid handling and manipulation applications. In addition, the simple nature of this fabrication technique allows device designs to be scalably manufactured and deployed with minimal time, equipment and training requirements. This new platform democratizes the field of microfluidics and offers budget-friendly technology for both academic device prototyping and largescale commercial device production.

“…Paper-based analytical methods have been used in scientific research or application areas for many years, the first being applied in the 19th century with the invention of the pH measuring tool, litmus paper. The mass flow of the paper that was used in the test strip depends on many factors for paper structures, including specific surface area, capillary flow, pore size, paper thickness, and porosity [37]. Currently, the carrier materials of paper-based analyses include three categories: cellulose, modified or compounded cellulose, and non-cellulose.…”

An aptamer is a synthetic oligonucleotide, referring to a single-stranded deoxyribonucleic acid or ribonucleic acid ligand produced by synthesis from outside the body using systematic evolution of ligands by exponential enrichment (SELEX) technology. Owing to their special screening process and adjustable tertiary structures, aptamers can bind to multiple targets (small molecules, proteins, and even whole cells) with high specificity and affinity. Moreover, due to their simple preparation and stable modification, they have been widely used to construct biosensors for target detection. The paper-based sensor is a product with a low price, short detection time, simple operation, and other superior characteristics, and is widely used as a rapid detection method. This review mainly focuses on the screening methods of aptamers, paper-based devices, and applicable sensing strategies. Furthermore, the design of the aptamer-based lateral flow assay (LFA), which underlies the most promising devices for commercialization, is emphasized. In addition, the development prospects and potential applications of paper-based biosensors using aptamers as recognition molecules are also discussed.
