Abstract

In this study, our aim is to introduce a novel technique that allows for direct collection of airborne biological particles on SERS substrates and in situ SERS analysis by modifying an inertial impactor, a conventional air sampler based on inertial force. This technique not only enables real-time detection of airborne biological particles without the need for sample preprocessing but also provides identification capability. As a result, it could serve as a simple, portable detection system for monitoring airborne biological particles and is expected to be useful in various atmospheric environment monitoring fields.
