“…More recently, Kunihisa et al (2020) reported sensitive SERS measurement of Aitken mode particles (<100 nm) by combining a condensational growth tube sampler (CGT) and a SERS substrate for directly sampling (Kunihisa et al, 2020). The wide analytical range of particle size enables SERS to be a potentially powerful tool in studying ambient particulate matters (Steer et al, 2016;Vejpongsa et al, 2017;Chen et al, 2021).…”

Single-particle Raman spectroscopy for studying physical and chemical processes of atmospheric particles

Abstract. Atmospheric particles experience various physical and chemical processes and change their properties during their lifetime. Most studies on atmospheric particles, both in laboratory and field measurements, rely on analyzing an ensemble of particles. Because of different mixing states of individual particles, only average properties can be obtained from studies using ensembles of particles. To better understand the fate and environmental impacts of atmospheric particles, investigations on their properties and processes at a single-particle level are valuable. Among a wealth of analytic techniques, single-particle Raman spectroscopy provides an unambiguous characterization of individual particles under atmospheric pressure in a non-destructive and in situ manner. This paper comprehensively reviews the application of such a technique in the studies of atmospheric particles, including particle hygroscopicity, phase transition and separation, and solute–water interactions, particle pH, and multiphase reactions. Investigations on enhanced Raman spectroscopy and bioaerosols on a single-particle basis are also reviewed. For each application, we describe the principle and representative examples of studies. Finally, we present our views on future directions on both technique development and further applications of single-particle Raman spectroscopy in studying atmospheric particles.

“…However, they could be detected with a SERS substrate. The sensitive detection by SERS can provide valuable insight into particle transformations and emission sources (Vejpongsa et al, 2017;Ghosal and Wall, 2019;Lee et al, 2019). However, the enhancement factor of SERS is not constant.…”

(Vejpongsa et al, 2017;Steer et al, 2016;Chen et al, 2021) Some species including components of microorganisms (Tahir et al, 2020), microplastics (Xu et al, 2020a), crystalline silica (Zheng et al, 2018), the fine structure of organics (Craig et al, 2015;Gen et al, 2018;Fu et al, 2017), and even some Raman-active inorganic salts at very low concentration (Saniel et al, 2019) are invisible in normal Raman due to their weak Raman-activities. However, they could be detected with a SERS substrate.…”
