Researchers describe how to efficiently merge microdroplets using electric field

In microfluidic devices, small separated droplets flow in a stream of carrier liquid. Occasionally, selected droplets have to be merged to carry out a chemical reaction. This can be greatly facilitated with the use of electric field, through a process of electrocoalescence that has been used industrially in large scale applications. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have found the laws governing the process and how to maximise the efficiency of merging.
