Abstract
Recent development in microsystems and microfuidics has made possible systematic fluid dynamics studies to understand the microscale flow physics and to evaluate the performances of microdevices. Both qualitative and quantitative microflow diagnostic techniques, such as fluorescent dye visualization, confocal imaging of three-dimensional flow structure, and micro-PIV, have been developed to analyze co-current immiscible liquids in a microchannel fabricated in poly (dimethylsiloxane) (PDMS). To manipulate biological or chemical samples in biomedical microfluidic systems, it is essential that we should fully understand the low Reynolds number micro/nanohydrodynamics governing the microflow behavior at the micro/nano scale.
