Airborne microorganisms pose a significant health threat, causing various illnesses. Traditional detection methods are often slow and complex. This review highlights the potential of nanomaterial-based biosensors, particularly colorimetric sensors, for rapid and on-site detection of airborne microbes. Colorimetric sensors offer real-time visual detection without complex instrumentation. We explore the integration of these sensors with Lab-on-a-Chip technology using PDMS microfluidics. This review also proposes a novel PDMS-based colorimetric biosensor for real-time detection of airborne microbes. The sensor utilizes a color change phenomenon easily observable with the naked eye, simplifying analysis and potentially enabling point-of-care applications.
空气传播的微生物对健康构成重大威胁，会引发各种疾病。传统的检测方法往往既缓慢又复杂。本综述强调了基于纳米材料的生物传感器，特别是比色传感器，在快速现场检测空气传播微生物方面的潜力。比色传感器无需复杂仪器即可进行实时视觉检测。我们探讨了使用聚二甲基硅氧烷（PDMS）微流体技术将这些传感器与芯片实验室技术集成。本综述还提出了一种新型的基于PDMS的比色生物传感器，用于实时检测空气传播的微生物。该传感器利用肉眼易于观察到的颜色变化现象，简化了分析过程，并有可能实现即时护理应用。
