The purpose of this article is to review the potential for application of light scattering as a means to detect and measure nanoparticle aerosol systems. Key results are feasibility calculations for scattered intensity, anisotropy, and intensity correlation times relevant for both static and dynamic light scattering measurements. These calculations are set in the context of background scattering from the suspending gases and the growth of the particulate system via aggregation. Some specific examples are given, but general concepts are presented as recommendations to allow reader to plan their particular experiments.
