Abstract: An improve microfluidic device (10) is configured to improve in microyalve system, the microfluidic device is in the form of rotary compact disc, comprising four substrate which a first substrate (20) having at least main reservoir (22) and secondary reservoir (24) containing working fluid (26), a second substrate (30) with at least a microvalve in the formed of diaphragm (32) structure which is actuated by the working fluid (26), a third substrate (40) with at least one reservoir (46) for fluid sample (44) and a microfluidic structure (42) as fluid sample pathway and a fourth substrate (50) with at least one microchannel (54) as an air flow passage. The microfluidic device has improved the valve system by applying a microchannel (54) that has at least two vent holes (52) and constriction feature (56) to allow and accelerate air from external environment to flow and generate pressure difference in order to cause the movement of said working fluid (26) for the working fluid to move the passive microvalve.

Abstract: The present invention relates to an apparatus for sorting particles by dielectrophoresis. The apparatus comprises of a primary microchannel (110), at least one side microchannel (120), and at least three electrically coupled electrodes (131, 132, 133). The electrodes (131, 132, 133) are arranged in the primary microchannel (110) and are positioned near the proximal end of the side microchannel (120). A first electrode (131) is a planar electrode forming a part of the bottom inner surface of the primary microchannel (110). A second electrode (132) is a planar electrode forming a part of the top inner surface of the primary microchannel (110). A third electrode (133) is a comb-like electrode suspended in the middle of the primary microchannel (110) and planarly inclined towards the side microchannel (120).
