1. A system for forming particles, the system comprising:

  • a conduit with a lumen having a first cross-sectional dimension and having an inlet and an outlet;

    an extruder having an inlet and an extruder orifice as an outlet located within the conduit, the extruder orifice having a second cross-sectional dimension that is smaller than the first cross-sectional dimension;

    a carrier fluid reservoir fluidly coupled with the conduit inlet;

    an extruder reservoir fluidly coupled with the extruder inlet;

    a particle collector fluidly coupled with the conduit outlet, wherein the particle collector has a collector inlet with a first temperature and a collector outlet with a second temperature that is lower than the first temperature with a temperature gradient between the first temperature and second temperature, wherein the collector inlet is coupled with the conduit outlet and the collector outlet is opposite of the collector inlet with a particle collector chamber between the collector inlet and collector outlet;

    the particle selector having a waste outlet opposite of the collector inlet; and

    a particle selector in the particle collector, wherein the particle selector is configured to direct particles to the collector outlet or the waste outlet.
