Recent studies have revealed the 'Marangoni bursting' effect of bicomponent droplets on oil bases, where they spread and atomize spontaneously due to solutal Marangoni forces. This research focuses on understanding how the basal oil film affects droplet spreading dynamics. We use high-speed imaging with laser induced fluorescence and particle imaging velocimetry to simultaneously track droplet spreading and the flow field in the oil base, allowing for scaling analysis to describe these dynamics. The insights provide quantitative knowledge of how oil base properties influence droplet behavior, which help to understand the liquid behaviors in liquid-liquid systems.
