Atmospherically relevant core-shell aerosol studied using optical trapping and Mie scattering
Abstract:
Solid core-liquid shell aerosols have been trapped in a counter-propagating optical trap confirming potential core-shell morphology in the atmosphere. Mie spectroscopy can be used to measure the core radius and film thickness to 0.5 and 1 nm precision respectively and to measure the wavelength dependent refractive indices of silica (core) and oleic acid (shell).
