摘要
A combination of photolithography and stereolithography was successfully used to fabricate a hybrid axisymmetric flow-focusing device (h-AFFD) that produces monodisperse picoliter droplets. The h-AFFD achieved the same level of hydrodynamic performance as a monolithic AFFD produced by only stereolithography from acrylic resin. Since the h-AFFD had a narrower orifice (50 or 100 mu m in diameter), created in an SU-8 sheet by photolithography, than the monolithic AFFD, we were able to produce picoliter droplets. We also succeeded in producing monodisperse droplets encapsulating a single cell without any surface modification.
