Abstract:
1. A method for synthesizing polymeric microstructures comprising: flowing a monomer stream, at a selected flow rate, through a fluidic channel; projecting at least one shaped pulse of illumination to the monomer stream, defining in the monomer stream a shape of at least one microstructure corresponding to the illumination pulse shape while polymerizing that microstructure shape in the monomer stream by the illumination pulse; and providing a polymerization termination species at internal walls of the fluidic channel to terminate at the channel walls active polymerization sites at which polymerization could occur during polymerization of a microstructure, such that polymerization is quenched at those sites and a non-polymerized volume of the monomer stream is preserved adjacent to the channel walls.
