Research topics

Team 11 carries out research on microfluidic techniques used in chemistry, biochemistry, and microbiology. At the core of our scientific interests are two-phase flows, i.e. micro-scale fluid flows which don’t mix together. Through manipulation of these immiscible flows, we can very rapidly establish optimal conditions for chemical synthesis, determine antibiotic susceptibility of bacteria, and examine the evolution of bacteria under different chemical conditions. We also create solutions for medical diagnostics.
