Abstract
A microfluidic device for controlled encapsulation of particles of sub-millimetric dimensions, or clusters of such particles, the device comprising: a first duct for delivering a first liquid phase containing particles for encapsulating in suspension; a second duct for conveying a flow of a second liquid phase that is immiscible with said first liquid phase; the first duct opening out into the second duct and forming a fluidic junction therewith; at least one microfluidic duct for discharging the first liquid phase flowing in said first duct and provided with a mouth located upstream from said junction and liable to be obstructed, at least in part, by a particle in suspension, thereby causing pressure to rise in the first duct. The invention also provides a microfluidic system including such a device, and a method of encapsulation based on using such a device.
