Recent Advances in Smart Phone-Based Biosensors for Various Applications

The demand of biosensors for field testing is increasing in various application scenarios such as food testing, environmental analysis, and medical diagnostics. However, conventional non-intelligent biosensors have been largely restricted in such applications. With the popularity of smart phones, biosensors combined with smart phones have successfully solved these problems. Acting as both analytical instruments and data platforms, smart phones have greatly improved optical and electrical biosensors for field testing. Importantly, coupled with cloud computing and artificial intelligence algorithms, smart phone-based biosensors enable real-time and dynamic testing and monitoring. This review focuses on how smart phones are combined with biosensors and what their combination methods are. At the same time, it introduces how their combination is applied in medical diagnostics, food testing, environmental analysis, and other aspects. Smart phones will enhance their crucial role in field testing, while simultaneously promoting technological innovation and interdisciplinary integration. With breakthroughs in other technologies, smart phone-based biosensors are poised to play an important character role in the future.
