Abstract

Aerosol droplets are trapped and manipulated with a single-beam gradient-force optical trap for timescales of hours. By coupling the optical trap with cavity enhanced Raman scattering, the size of the trapped droplet can be determined with nanometre accuracy and high time resolution. This allows the evolution in droplet size and composition to be monitored during the growth or evaporation of a single trapped droplet, providing a method for characterising the factors that govern aerosol droplet size. The simultaneous trapping of two or more aerosol droplets in parallel optical traps can permit studies of aerosol coagulation.
