Tailored nanoliter single and double emulsions that can be transported, collected/chained, and purposefully fused using magnetophoretic techniques are demonstrated. We show that such emulsions can be used for mixing, release and reaction of minor amounts of encapsulated cargo with spatial and temporal control, offering promise in applications requiring on‐demand cargo release and in droplet‐based...
Magnetically responsive nanoliter droplets enable on‐demand release of encapsulated cargo using magnetic fields as an external trigger, say A. R. Studart and co‐workers on page 2582. The droplets are made from monodisperse double emulsions produced in a glass capillary micro‐fluidic device. Magnetic response is achieved by adding superparamagnetic nanoparticles to the inner or intermediate phase of...
Macroporous polymers are attractive materials due to their low density, low cost, recyclability and tunable mechanical and functional properties. Here, we report a new approach to prepare macroporous polymers from emulsions stabilized with colloidal polymeric particles in the absence of chemical reactions. Stable water-in-oil emulsions were prepared using poly(vinylidene difluoride) (PVDF), poly(tetrafluoroethylene)...
