免疫分析是在临床和研究实验室中对广泛的生物分子分析物进行灵敏和定量分析的有力工具。然而,酶联免疫吸附测定(ELISA)-金标准测定-需要大量的用户干预,时间和临床资源,使其部署在护理点(POC)不切实际。研究人员已经在POC和可负担的价格上民主化获得临床质量免疫测定方面取得了长足的进步。在这篇评论中,我们首先总结了商业上可用的选项,提供高性能,虽然在高成本。接下来,我们描述了用于开发节约POC测定的策略,该测定重新利用消费电子产品和智能手机来定量检测分析物。最后,我们讨论了创新的检测格式,使高灵敏度的分析,在现场与简单的仪器。
Immunoassays are a powerful tool for sensitive and quantitative analysis of a wide range of biomolecular analytes in the clinic and in research laboratories. However, enzyme-linked immunosorbent assay (ELISA)—the gold-standard assay—requires significant user intervention, time, and clinical resources, making its deployment at the point-of-care (POC) impractical. Researchers have made great strides toward democratizing access to clinical quality immunoassays at the POC and at an affordable price. In this review, we first summarize the commercially available options that offer high performance, albeit at high cost. Next, we describe strategies for the development of frugal POC assays that repurpose consumer electronics and smartphones for the quantitative detection of analytes. Finally, we discuss innovative assay formats that enable highly sensitive analysis in the field with simple instrumentation.
