A microfluidic sensor for dynamic surface tension measurement
A novel microfluidic sensor for measuring dynamic gas-liquid interfacial tension is reported. The device consists of a microfluidic chip with a microchannel network and an optical detection system. The sample is introduced ...
A method for simultaneously determining the zeta potentials of the channel surface and the tracer particles using microparticle image velocimetry technique
The zeta potentials of channel surfaces and tracer particles are of importance to the design of electrokinetic microfluidic devices, the characterization of channel materials, and the quantification of the microparticle ...
Investigation of active interface control of pressure driven two-fluid flow in microchannels
We report a novel concept to control the interface location of a pressure-driven multi-phase flow in a microchannel by using electroosmotic flow effects. This concept has potential applications in flow switching and cell ...
