Popis: The ability to control liquid transfer is of fundamental interest in droplet-based microfluidics. Here, we present a method that allows the selective transfer of fluid by means of a gas bubble injected into a liquid droplet. Two mechanisms were studied, one being liquid transfer through the detachment of a liquid bridge, which results in transfer of over 90% of the droplet between substrates in a single step. The other mechanism is liquid transfer via jetting at the moment of bubble rupture; in this case, a smaller daughter droplet is created on the recipient substrate.
