Aerosol droplets have significant effects on atmospheric photochemistry, however measuring absorption from single droplets is a challenge. Here, the authors report a method to measure absorption of nanodroplets with attolitre sensitivity, showing rate enhancements for light focusing in photolysis reactions.
