Microfluidic research has been motivated by the increasing
need to manipulate small amounts of fluids, often for the purpose of
fast analysis of biological and chemical samples. An
important issue in microfluidics is the control of fluid interfaces, in
particular the generation and manipulation of droplets in lab-on-a-chip
devices. Applications range from analytical chemistry to controlled
release to micro-engineered materials with specialized biological,
chemical and optical properties.
In collaboration with Professor Amy Shen of the University of Washington, we are investigating experimentally and computationally the formation and manipulation of droplets of liquid crystals in microfluidic channels.
