Toluene, naphthalene and derivates can not only be detected in water, but also in the air either as gases or aerosols. Therefore, developing platforms suitable for their detection is also of significant importance. In the work of Phan-Quang et al., the authors applied the SERS substrate made by multilayered Ag@ZIF-8 nanocubes (discussed in Section 2.3 of this manuscript) for the stand-off detection of such VOCs. A system composed of SERS substrate and spectrometer was deployed outdoor and aerosolized mixtures of Toluene and Naphthalene in different ratios were ejected in the vicinity of the SERS substrate (Figure Copyright 2019, The Royal Society of Chemistry.
