抽象的。大气颗粒物经历各种物理和化学过程,并在其生命周期内改变其性质。大多数对大气颗粒物的研究,无论是在实验室还是野外测量,都依赖于对颗粒物集合的分析。由于单个粒子的混合状态不同,使用粒子系综的研究只能获得平均性质。为了更好地了解大气颗粒物的命运和对环境的影响,在单个颗粒物水平上对其性质和过程进行研究是有价值的。在丰富的分析技术中,单粒子拉曼光谱以非破坏性和原位的方式提供了在大气压下对单个粒子的明确表征。本文综述了这一技术在大气颗粒物研究中的应用,包括颗粒吸湿性、相变和分离、溶质-水相互作用、颗粒pH和多相反应。综述了单粒子增强拉曼光谱和生物气溶胶的研究进展。对于每一种应用,我们都描述了研究的原理和代表性的例子。最后,对单粒子拉曼光谱在大气颗粒物研究中的技术发展和应用前景提出了自己的看法。
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.
