Gas-phase detection using SLIPSERS. (A) Schematic showing the experimental procedures for airborne species detection. (B) SERS spectra of 4-ATP captured on the Au nanoparticle aggregate exposed to the 4-ATP environment at different amounts of time. After exposing for 10 min, most of the Raman peaks of 4-ATP molecules are distinguishable.
