Microfluidic fabrication of smart micro gels from macromolecular precursors

Results

Microuidic emulsication of a semidilute solution of crosslinkable pNIPAAm precursors in water (schematic). Subsequent gelation of the monodisperse droplets, achieved through crosslinking the polymer chains by dimerization of pendant reactive side groups, forms monodisperse microgel particles.
