In vitro diagnosis (IVD) is a hot topic in laboratory research and achievement transformation. Microfluidic paper-based analytical devices (μPADs) have played a significant role in advancing the development of IVD. This paper provides a comprehensive review of μPAD classification and research progress in IVD, and discusses the potential improvements in terms of portability, sensitivity, and automation.
In vitro diagnosis (IVD) has become a hot topic in laboratory research and achievement transformation. However, due to the high cost, and time-consuming and complex operation of traditional technologies, some new technologies are being introduced into IVD, to solve the existing problems. As a result, IVD has begun to develop toward point-of-care testing (POCT), a subdivision field of IVD. The pandemic has made governments and health institutions realize the urgency of accelerating the development of POCT. Microfluidic paper-based analytical devices (mu PADs), a low-cost, high-efficiency, and easy-to-operate detection platform, have played a significant role in advancing the development of IVD. mu PADs are composed of paper as the core material, certain unique substances as reagents for processing the paper, and sensing devices, as auxiliary equipment. The published reviews on the same topic lack a comprehensive and systematic introduction to mu PAD classification and research progress in IVD segmentation. In this paper, we first briefly introduce the origin of mu PADs and their role in promoting IVD, in the introduction section. Then, processing and detection methods for mu PADs are summarized, and the innovative achievements of mu PADs in IVD are reviewed. Finally, we discuss and prospect the upgrade and improvement directions of mu PADs, in terms of portability, sensitivity, and automation, to help researchers clarify the progress and overcome the difficulties in subsequent mu PAD research.
