Microfluidic devices are provided where barriers are introduced between different compartments of the device to prevent fluid flow between the two compartments. Different materials and methods are employed for the introduction and removal of the barriers, including reversible gel particle expansion, reversible gellation, in situ polymerization, magnetic beads, and the like. In this way mixing of agents may be temporally controlled during the operation of the device, where the barriers may be used in a passive manner or as an active agent involved in the operation being performed in the device.
微流体设备可在设备的不同隔室之间引入屏障,以防止流体在两个隔室之间流动。采用不同的材料和方法来引入和移除屏障,包括可逆凝胶粒子膨胀、可逆凝胶化、原位聚合、磁珠等。通过这种方式,可在设备运行过程中对药剂的混合进行时间控制,其中屏障可以被动方式使用,也可以作为主动药剂参与设备中正在进行的操作。
