Abstract
The invention relates to a method and devices for the production of capillary microjets and microparticles that can have a size of between hundreds of micrometers and several nanometers. The inventive method makes use of the combined effects of electrohydrodynamic forces, fluid-dynamic forces and a specific geometry in order to produce micro- and nano-capsules or fluid jets, single- or multi-component, which, upon disintegrating or splitting, form a significantly monodispersed spray of drops which have a controlled micro- or nanometric size and which can also comprise a specific internal structure, such as, for example, a nucleus which is surrounded by a cortex of a different substance or several concentric or non-concentric nuclei or vesicles which are surrounded by a cortex.
