Abstract

Airborne pathogens pose a great threat to public health, and their appearance in bioaerosol also increases the contiguousness due to the long survival time and transmitting range. Real-time monitoring and rapid detection methods provide more effective prevention and control of airborne pathogens. The whole procedure could be divided into bioaerosol collection and detection processes. This review presents the basic principles and recent advances in commonly used methods for each of these two steps. We categorized four different kinds of collection methods based on their principles and discussed possible enrichment methods against a small amount of targets. Four different detection methods were compared regarding their ability to perform rapid testing. In the final section, we analyzed the latest trend in combining all these steps to set up a single device or platform for rapid, automated, and continuous on-site bioaerosol monitoring to overcome time and space constraints and increase the speed of the entire monitoring process. We conclude that an integrated all-in-one system using a microfluidic platform is the most promising solution for real-time monitoring of airborne pathogens, since they are capable of simplifying operational steps, efficient collection, and high-throughput detection, demonstrating the strong potential of field-deployable platforms.

现场监测空气中的病原体：生物气溶胶收集和快速检测的最新进展

空气传播的病原体对公众健康构成巨大威胁，它们在生物气溶胶中的出现也因存活时间长、传播范围广而增加了传染性。实时监测和快速检测方法可以更有效地预防和控制空气传播的病原体。整个过程可分为生物气溶胶收集和检测过程。本综述介绍了这两个步骤的基本原理和常用方法的最新进展。我们根据原理对四种不同的收集方法进行了分类，并讨论了针对少量目标可能采用的富集方法。我们还比较了四种不同的检测方法的快速检测能力。最后，我们分析了最新的趋势，即把所有这些步骤结合起来，建立一个单一的设备或平台，进行快速、自动和连续的现场生物气溶胶监测，以克服时间和空间的限制，提高整个监测过程的速度。我们的结论是，使用微流控平台的一体化多合一系统是实时监测空气传播病原体的最有前途的解决方案，因为它们能够简化操作步骤、高效采集和高通量检测，展示了现场可部署平台的强大潜力。
