摘要： Lateral flow immunochromatographic strip is one of the mainstream rapid detection products in the current market. Smartphones with built-in high-definition cameras have been popular among consumers in recent years. By taking a picture via mobile phones, then analyzing with machine vision image recognition technology, the optical signal of strip developed color could be converted into digital signal based on visible light colorimetric analysis or fluorescence analysis technology. This has become a research hotspot of rapid detection to realize qualitative or quantitative determination based on strip color development in recent years. In this paper, the applications of rapid detection technology based on smartphone and lateral flow immunoassay in medical diagnosis, environmental monitoring and food safety were reviewed. Moreover, the quantitative detection mode, implementation method and challenges of rapid test strip products based on smartphone photography were also discussed and summarized, which could provide reference for its realization of multi- target analysis, on-site rapid qualitative and quantitative detection.
