Secondary Microflows in Electrokinetic Transport with Hydrodynamic Slippage Effect

Kim K.S., Chun M.-S., Byun Y.T., Woo D.H., Korea Institute of Science and Technology (KIST), KR

The curved microchannel is frequently encountered in the lab-on-chips because it provides a convenient way for increasing channel length per unit area. The behavior of electrokinetic flow with curvature-induced secondary motion was explored based on [...]

Evanescent wave-based particle tracking technique for velocity distribution in extended nanochannel

Kazoe Y., Iseki K., Mawatari K., Kitamori T., The University of Tokyo, JP

We developed a flow measurement technique of velocity distribution in extended nanochannel (10- 1000 nm), using fluorescent tracer nanoparticles and the evanescent wave which penetrates into a liquid medium with an exponential decay from the [...]
