Abstract

The invention relates to a production method for a device intended to disperse or 'focus' a fluid in a precise, controlled manner at a micrometer scale, using the flow focusing technique and devices produced in accordance with said method. According to the invention, the method enables the simple production of a device that can produce coaxial flows of fluids (three-dimensional encapsulation). The production process, which is based on standard techniques used in microsystem technology (microelectromechanical systems or MEMS), enables the low-cost mass production of dispersion devices having micrometer precision and a very reduced size. The device produced can be easily built into two-dimensional matrices and coaxial flows can be created in the direction perpendicular to the matrix
