A schematic of the Fluidic NanoPrecipitation System (FNPS). (A) Cartoon of FNPS. Sample inlets are inserted into the dispersing channel. The inlet channel contains PLGA polymer that precipitates upon contact with the surfactant in the dispersing channel, freezing the particles in a spherical morphology. (B) Side view of the channel. PLGA droplets are exposed to the hydrodynamic force of the continuous flow.
