碩士 === 國立中興大學 === 機械工程學系 === 93 === The goal of this study is to address geometry effect on the analyte band dispersion in electrokinetic-driven microchannel flow. Loading, dispensing, and dispersion of an analyte band are examined by both numerically and experimentally in three types of microchannels: straight channel, 90 degree turn, and 180 degree turn. The numerical simulation is carried out using Femlab software while experiment are carried out on a chip fabricated using microfabrication technology. Based on the qualitative agreement between the numerical and experimental results, several optimizations design of the channel geometry leading to minimize the band dispersion are demonstrated using numerical simulation.
