Abstract

A method by which the microfluidic chip can be used for the electrically controlled synthesis of new types of supraparticle is described. The method is based on a technique that allows freely suspended droplets and particles to be entrapped and transported using electric fields. Each of the microdroplets suspended on the surface of fluorinated liquid serves as a microscopic reactor, where the particles are formed by solidification of the carrier droplets. The method can also be used to entrap and manipulate both the liquid droplets and the resultant solid particles by electric fields.
