A new μTAS(micro total analysis systems) for biochemical analysis is introduced, including the design and fabrication techniques for the capillary electrophoresis (CE)chip,the microprocessor system and the initial experiment result. The new CE chip based on linear-arrayed electrode is capable to change the experiment conditions flexibly, such as separation time, distance and driving voltage etc, and to meet the needs of many separation. The control kernel of the system is single chip processor C8051F020, an...
