The microfabricated microfluidic system has been optimized for application in capillary electrophoresis\u2013electrochemical\n detector (CE-ECD), polymerase chain reaction (PCR) and microcantilever. The system is realized by means of a polydimethylsiloxane (PDMS)-glass chip and indium tin oxide heater. The pumping rates of the proposed micropump are measured as functions of the frequency and the duty-ratio of applied\n voltage. The performances of the microvalves are characterized under the on\/off alternation with the applied power of the indium tin oxide (ITO) heater. The flow rate gradually decreases as the applied heater power increase. The optimized membrane thickness for microfluidic system is 350 <jats:italic>\u03bc<\/jats:italic>m.\n At this condition, the power of the cut-off flow in microvalve is 400 mW and the 70 nl\/min of maximum pumping rate is observed at a duty ratio of 4% and a frequency of 4 Hz for the applied pulse power.<\/jats:p>","DOI":"10.1166\/jnn.2008.ic83","type":"journal-article","created":{"date-parts":[[2008,8,6]],"date-time":"2008-08-06T00:31:15Z","timestamp":1217982675000},"page":"4588-4592","source":"Crossref","is-referenced-by-count":8,"title":["Microfabricated In-Channel Structured Polydimethylsiloxane Microfluidic System for a Lab-on-a-Chip"],"prefix":"10.1166","volume":"8","author":[{"given":"Gyu-Sik","family":"Ra","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong-Chul","family":"Yoo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.
