“…Microfluidic channels have been extensively used due to their inherent high-throughput way of operation [4,5]. In microparticle fabrication, one important issue is to control the shape of the microparticles, which is typically realized through two-phase fluid systems [5][6][7] or continuous flow lithography [3,4,8]. Thus, it is essential to understand drop dynamics in two-phase systems to generate a targeted shape.…”
