Microfluidic Platform for the Generation of Polymer Colloids

 

Zuzanna T. Cygan, Kathryn L. Beers, and Eric J. Amis

 

We demonstrate a microfluidic platform for the synthesis of polymer particles of controlled size and composition.  Rapid prototyping photolithography of a thiolene-based resin was used to fabricate microfluidic devices stable to organic solvents and monomers.  Monodisperse droplets of monomer suspended in a water/surfactant matrix were formed and photopolymerized on chip to generate crosslinked polymer particles.  In-line Raman spectroscopy and image analysis were used to monitor extent of conversion and particle size and composition.
