This book presents a comprehensive overview of the development, deployment, and future potential of biosensors in addressing air pollution and atmospheric health challenges. It explores cutting-edge platforms for monitoring airborne particulates, volatile organic compounds, heavy metals, toxic industrial gases, and bioaerosols, with emphasis on urban and indoor air quality, wearable and mobile sensing devices, and drone- and satellite-assisted monitoring networks. The book covers the application of advanced materials, biorecognition elements, and signal transduction mechanisms for gaseous and aerosol detection. It also examines the integration of biosensors with IoT and remote sensing technologies, enabling scalable and intelligent air quality monitoring systems. This book is an invaluable resource for researchers, engineers, environmental scientists, and public health professionals dedicated to protecting atmospheric and environmental health through modern sensing solutions.
