Abstract
Individual micron-sized solid particles from a Salamol® pharmaceutical inhaler are stably captured in air using an optical trap for the first time. Raman spectroscopy of the levitated particles allows online interrogation of composition and deliquescent phase change within a high humidity environment that mimics the particle's travel from inhaler to lung.
