Abstract
A method for detecting chemical aerosols and particulates on a surface by contacting a sample with a Surface Enhanced Raman Spectroscopy (SERS) substrate where the sample is an aerosol or a particulate on a surface, encapsulating the SERS substrate with the sample, heating the encapsulated sample so it vaporizes inside the encapsulation, cooling the vaporized sample so it deposits onto the SERS substrate, and irradiating the SERS substrate to collect a SERS spectrum of the sample. Also disclosed is the related system for detecting chemical aerosols and particulates on a surface.
