RIKEN MICROFLUIDICS LAB
We actively study problems involving fluid dynamics and transport phenomena in micro/nano confined spaces. The problems are inspired by microfluidic systems for biochemical analysis and cellular engineering. Especially, we are interested in electrokinetic phenomena, e.g., electrophoresis, electroosmotic flow, and electrowetting, of complex fluids including cells and biomacromolecules. We use various approaches of experiments, numerical simulation, and modeling to explore the problems. Major methods in experiments are optical flow observations based on fluorescence microscopy, micro-PIV (particle image velocimetry), high precision current/voltage measurements, and micro fabrications. We also leverage theoretical and numerical analyses based on fluid mechanics to understand the physics underlying the phenomena observed in experiments. See more detail in our recent publications.
