We are presenting an all-optical platform for on-demand and nonintrusive studies of
coalescence of micron-sized liquid droplets in air. The platform has the purpose to mimic the …

A new experimental technique for creating and imaging collisions of micron-sized droplets
settling under gravity is presented. A pair of glycerol droplets is suspended in air by means …

In this paper a versatile experimental system for optical levitation is presented. Microscopic
liquid droplets are produced on demand from piezo-electrically driven dispensers. The …

Förster Resonance Energy Transfer (FRET) is a radiationless distance-dependent transfer of
energy from an excited donor fluorophore to an acceptor fluorophore. This radiationless …
