Immunoassay has been routinely used in hospitals and central labs. Nowadays, to further meet the requirement of widespread applications of immunoassays, it is urgently needed to produce a simplified, rapid and low-cost immunoassay to perform tests on site. To this end, paper-based point-of-care (POC) immunoassays have attracted intensive interests in recent years. In this paper, we present a comprehensive review of the recent advances and emerging trends of paper-based POC immunoassays, including the fundamental components and work principles, various detection mechanisms and applications, and existing commercialized devices/products. At last, we envision three promising development directions for paper-based POC immunoassays.
免疫测定已在医院和中心实验室中常规使用。如今,为了进一步满足免疫测定广泛应用的要求,迫切需要开发一种简化、快速且低成本的免疫测定方法,以便在现场进行测试。为此,近年来基于纸张的即时检测(POC)免疫测定引起了人们的浓厚兴趣。在本文中,我们全面回顾了基于纸张的 POC 免疫测定的最新进展和新兴趋势,包括基本组件和工作原理、各种检测机制和应用以及现有的商业化设备/产品。最后,我们展望了基于纸张的 POC 免疫测定的三个有前途的发展方向。
