The present invention relates to a micro-fluidic device for use in a micro-fluidic system. A rigid base structure is provided with a flexible membrane. An external magnetic driver moves from a first position to a second position underneath the micro-fluidic device whilst applying a magnetic field. A droplet containing magnetic particles will be attracted to the external magnetic driver. The flexible membrane is thin, and therefore the micro-fluidic device can be brought closer to the external magnetic driver, thus increasing the magnetic force incident on the fluid drop. A force will be exerted on the flexible membrane, so deflecting the flexible membrane, thus bringing the droplet containing magnetic particles closer to the external magnetic driver. The effect of the increased magnetic field is to increase the packing density of the magnetic droplet. Therefore, a droplet with higher integrity, and less susceptible to splitting, may be moved through the micro-fluidic device. 本发明涉及用在微流控系统中的微流控设备。刚性底座结构设置有柔性膜。外
