Fabrication of microgel particles with complex shape via selective polymerization of aqueous two-phase systems

Small. 2012 Aug 6;8(15):2356-60. doi: 10.1002/smll.201102715. Epub 2012 May 31.


Microgel particles are formed from aqueous-two-phase-system (ATPS) droplets in poly(dimethylsiloxane) (PDMS) microfluidic devices. The droplets consist of a dextran core and a photopolymerizable poly(ethylene glycol) diacrylate (PEGDA) shell. Upon UV exposure, the ATPS droplets undergo a shape-transformation yielding PEGDA microgel particles containing a socket.
