A review on application of laser induced fluorescence spectroscopy in exploring bioaerosol characteristics

Atmospheric aerosols affect climate, ecosystems and human well-being. Accurate detection and classification of aerosols, particularly bioaerosols are essential for effective environment and public health management. This review presents an overview of Laser-Induced Fluorescence (LIF) Spectroscopy as a powerful approach for realtime, non-destructive aerosol analysis. It outlines the technological progression from foundational systems to modern commercial instruments such as the UV-APS, WIBS, BioScout and Rapid-E. These technologies have enabled detailed insights into aerosol size, composition and biological content, yet challenges in standardization and signal interpretation remain. By summarizing key findings and innovations, this paper 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.
