Volatile organic compounds (VOC) are emitted as vapors from certain solids or liquids, including a variety of chemicals with short- and long-term adverse health effects. Therefore, it is important to monitor the concentration of the vapors to safeguard the health of the workers, and also to keep atmospheric emissions under control in order to avoid environmental hazards. Optical sensors based on localized surface plasmon resonance (LSPR) for detecting of VOCs are possibly applied to a wide range of the field due to a simple construction and low cost. In this study, we describe the high sensitive and wide range (1-26000 ppm) LSPR sensor employing Au dot pattern with porous silica film.
