Abstract:
Atmospheric aerosols affect the climate, ecosystems and human well-being. Accurate detection and classification of aerosols, particularly bioaerosols are essential for effective environmental and public health management. This review presents an overview of laser-induced fluorescence (LIF) Spectroscopy as a powerful approach for real-time, non-destructive aerosol analysis. This study outlines the technological progression from foundational systems to modern commercial instruments such as the ultraviolet aerodynamic particle sizer, wideband integrated bioaerosol sensor, BioScout and Rapid-E. These technologies have provided detailed insights into aerosol size, composition and biological content, yet there are challenges in standardization and signal interpretation. By summarizing key findings and innovations, this study highlights the significance of expanding LIF applications in under-represented regions and encourages the development of robust, field-ready systems to advance air quality management and health safeguards.
