Abstract

Here we will show the methodology to prepare multiple topological defects in a microfluidic device. The topological defects were stabilized by optimizing the size and shape and satisfying the boundary conditions inside each micro-well. Furthermore, we introduced the liquid on liquid crystals by modifying the microfluidic device. The introduction of various liquidscould show a variety of alignments for the liquid crystals, which could provide topological defects in a well. When the photo-responsive molecules at the interfaces could control the on/off behavior of the topological defects. This is a new platform for studying the properties of topological defects and their functions.
